Treat calculation and report preparation as separate actions
An NDT worksheet can contain recorded observations, administrative totals and engineering calculations in adjacent columns. They do not have the same evidential meaning. Before transferring a result, identify whether it was measured directly, calculated from inputs or supplied as an interpretation by another person. The report should make that distinction clear enough for its intended recipient. A calculated value is not made trustworthy by placing it beside a measurement or by giving it more decimal places. The person preparing the document needs a supported value and a reference to the process that produced it.
Use the free reporting workspace to present reviewed information. It does not operate as a spreadsheet calculation engine or independently validate an engineering calculation. The decision to use a particular formula, its assumptions and its technical applicability belongs in the responsible organization’s controlled process. This guide addresses the transfer between that process and the report. It can help expose missing inputs or stale outputs, but it does not supply acceptance criteria, remaining-life decisions or a substitute for competent technical review. Keep those boundaries visible when selecting what belongs in a client-facing table.
Understand the difference between a formula and its saved result
Microsoft’s SpreadsheetML formula guidance describes formula content separately from the stored cell value. Consequently, reading an Office file is not the same action as recalculating its formulas. A workbook can carry an expression and a previously stored result that was created in another application session. A report preparer should not assume that a value extracted from the file represents a fresh calculation using the latest intended inputs. The expression, input state and calculation context need to be understood together before the output is relied upon.
NDT Connect deliberately leaves formula cells blank during supported XLSX template import and displays a warning. It does not use a saved formula result to imply that a calculation has been performed or verified. Check the preview for those blanks and return to the controlled calculation source when a result is needed. A blank formula cell is an invitation to complete the evidence review, not a zero result and not a reason to remove the row. Retain the row’s item identity so the checked value can later be placed in the correct location.
Identify which calculation the recipient actually needs
List the calculated fields requested by the deliverable and describe each in plain language. A total number of examination events differs from a total number of unique components, even when both appear under a heading called quantity. A converted display value differs from a new measurement. An engineering assessment output may depend on information that is absent from the result table. Confirm the intended question before checking the arithmetic. Otherwise, a mathematically correct answer can still mislead because it answers a different question from the one the customer believes it addresses.
For each field, record the calculation owner, source document and relevant revision. If a customer supplies a result to be reproduced, make its origin clear rather than presenting it as a calculation performed by the inspection provider. If the result is unnecessary for the agreed report, do not import it merely because it was present in a working spreadsheet. Select a defensible reporting scope. Removing an unnecessary intermediate calculation can improve clarity, provided the required supporting record remains available through the project’s actual document-control arrangements.
Freeze the input set before accepting an output
A transfer record should identify the input version used for the calculation. Record the source workbook identity, sheet or named range and the examination events represented. For a small calculation, the relevant input values may fit directly in the review record. For a large set, retain an unambiguous reference to the controlled dataset and the selection boundary. Avoid phrases such as latest data when the dataset can change after the report is prepared. The reviewer needs to know which values produced the reported output at the time it was accepted.
Watch for filters, hidden rows, repeated examinations and excluded items that alter the meaning of a total. A table displayed on screen may show fewer records than the formula addresses. Conversely, a manually selected range may omit a newly appended row. These are practical review questions, not assumptions that every spreadsheet has the same behavior. Ask the calculation owner to demonstrate which inputs are included. Record the inclusion rule in language the report recipient can understand, especially when administrative quantities are used to reconcile completed scope or support a commercial handover.
Confirm recalculation through the controlled source application
Microsoft documents automatic and manual recalculation options in Excel. That makes calculation state a legitimate review question. Ask the person responsible for the workbook how the accepted result was obtained after the relevant inputs were finalized. Simply opening a file, saving it or seeing a number on screen is not a complete statement of that review. Avoid changing another person’s calculation settings casually, particularly when other workbooks or linked inputs are involved. The responsible owner should control and explain the calculation action.
Keep evidence proportionate to the result’s significance. A simple administrative count may be checked against an independently reconciled item list. A technical result may require the organization’s approved calculation method and authorized review record. Do not apply the same casual check to both. If a link, named range or external input cannot be resolved, hold the affected result for clarification. The reporting editor does not fetch external workbook relationships during import. It cannot supply an absent input or establish which version of a remotely held workbook was intended.
Review units and display precision before copying the value
The output needs a unit where the quantity requires one, and the unit must match what the calculation actually returns. Keep the original value and unit distinguishable from a converted presentation. NIST’s guide to SI usage provides conventions for expressing quantities and unit symbols; it does not validate an NDT formula. Use the project’s agreed numerical presentation and review process. Do not infer extra measurement accuracy from the number of digits produced by a spreadsheet, or delete significant information merely to make a column narrower.
Record the exact approved display value that will appear in the report, including its unit and any necessary qualifier. If the source retains more digits, preserve that source rather than replacing it with the report’s rounded display. A reviewer should be able to distinguish the calculation result from its presentation. Do not use this transfer step to introduce a new rounding rule or a pass/fail threshold. Where the project requires a specific convention, identify its source and have the responsible person confirm how it applies to the result being reported.
Keep calculation evidence separate from technical disposition
A verified arithmetic result does not automatically establish that an examined item is acceptable. The calculation may address only one part of a broader assessment, and the governing criterion may come from another document or decision maker. In the report, distinguish the numerical result, the applicable reference and the user-entered disposition. If evaluation is pending, state that condition instead of turning a completed calculation into a completed inspection decision. The reader should not have to guess whether acceptable means the formula ran successfully or an authorized person evaluated the item.
The procedure draft workspace can help organize a draft description of reporting controls for responsible review. It does not approve the method or calculation. Similarly, the free calculator directory offers tools with their own assumptions that must be checked for applicability. A value copied from any calculator needs the same attention to inputs, units and review as a spreadsheet output. Retain enough evidence to reproduce the relevant administrative or technical reasoning through the approved process, without implying that the website has independently certified the result.
Create a deliberate transfer record instead of pasting blindly
Use one transfer row for each calculated output or clearly defined group of identical outputs. Include the source cell or result identifier, calculation reference, input version, checked output, report destination and reviewer or open action. The destination should identify the actual item and column, not only an unstable row number. This matters when the report table is sorted or additional rows are added. A value can be copied perfectly and still be wrong in context if it is pasted into a neighboring component’s record.
Enter only the checked display result into the report field intended for it. Keep the formula expression or detailed calculation in its controlled source unless the deliverable specifically calls for it. A narrative note can identify the calculation reference without reproducing a complex expression that the recipient might misunderstand. After entry, compare the report value back to the accepted transfer row. This reverse check catches misplaced units, dropped signs, accidental percentage formatting and values copied from a preliminary calculation instead of the reviewed one.
Worked example: two different totals in a closeout workbook
In a fictional closeout, an examination register contains ten unique component identifiers and one repeat examination of an already listed component. The deliverable asks for both unique components examined and examination events. An older summary cell still displays nine components, while a second cell counts eleven events. The coordinator does not copy either number merely because it is visible. The source owner reconciles the identifiers, confirms the inclusion rule and supplies the checked totals. This example concerns administrative quantities only; it does not establish examination coverage or technical acceptance for a real project.
The transfer record identifies ten unique components and eleven examination events as different outputs. It links the repeat event to its original component and records the source revision used for the count. After XLSX import, the formula cells are blank as expected. The coordinator enters the checked totals into clearly labelled report fields and compares them with the row-level record. The report explains the distinction so the recipient does not interpret eleven events as eleven different components. A final review checks that the repeated examination has not disappeared from the supporting table.
| Output | Question answered | Checked value | Required context |
|---|---|---|---|
| Unique component total | How many different component IDs were examined? | 10 | Confirmed identifier list and inclusion rule |
| Examination-event total | How many recorded examination events are included? | 11 | One event is a repeat on an existing component |
| Older summary cell | Does the saved display reflect the finalized input? | Not accepted | Source owner resolves the outdated value |
| Imported formula cell | Did the reporting editor calculate this output? | Blank | Enter a checked result after review |
Handle changed inputs before the report is distributed
If the underlying data changes after a result was checked, identify which outputs depend on the changed input. Do not assume every result needs recalculation, but do not carry forward a result without checking its dependency. Mark the affected transfer entries pending and obtain the revised calculation evidence through the same responsible process. A changed component identity can alter a unique-count total even when the number of table rows stays the same. A changed unit can affect an interpretation even when the displayed digits appear unchanged.
Compare the revised output with the earlier accepted value and explain any difference relevant to the recipient. Keep the report in draft while the changed result is unresolved. If an issued report is affected, follow the controlled amendment process and preserve the relationship to the earlier issue. The report amendment guide addresses that separate task. This transfer worksheet should supply the evidence needed for the amendment review, rather than becoming an informal route for replacing an issued result without explanation.
Check the exported values and their surrounding labels
Download the report PDF and verify the accepted result in the actual deliverable. Read the heading, value, unit and qualifying note together. Check that a minus sign, decimal separator or percent sign has not been lost or placed in a confusing position. For a calculated summary, compare its scope with the detailed rows visible in the same report. The final document should not invite an inference that conflicts with the transfer record, such as a total covering all requested work when excluded or unresolved items remain.
Use the inspection report buyer-review guide for the broader question of whether the package answers the requested scope. The formula-transfer check is narrower: it establishes which reviewed output was entered where and on what basis. It does not review every technical aspect of the examination. Keeping those review objectives separate makes gaps easier to see. A reviewer can confirm faithful transcription while still requiring a responsible technical person to resolve the calculation’s applicability or the final disposition.
Do not turn a source error into a plausible report value
If the source owner finds an error message, missing dependency or unexplained result, record the affected output as unresolved. Replacing an error with zero changes its meaning. Copying the previous report’s value can be equally misleading when the input set has changed. Ask which source condition prevents the calculation from being accepted and who can resolve it. Keep the affected component or summary identity visible so the unresolved calculation does not disappear when the working table is reorganized.
Where the report can legitimately proceed without that output, obtain the responsible decision and explain the resulting limit in the deliverable. Where it cannot, retain the draft until the required evidence is available. The relevant choice depends on the agreed reporting scope and technical significance, not on whether a blank cell looks untidy. A clear open item is more useful to the next reviewer than a convincing number whose origin nobody can support.
Retain enough information to answer a later challenge
A later recipient may ask why two reports show different calculated values for an apparently similar item. The useful response is a traceable explanation of the input set, calculation reference, presentation rule and examination context. Retain the controlled source and transfer evidence through the applicable project arrangements. Do not rely on a copied number in the PDF as the only surviving record of how it was produced. Equally, avoid an unstructured archive of every temporary workbook when a clear accepted source and its relevant history provide a more usable explanation.
The worksheet is complete when each transferred result has an identified origin, a resolved input state, a checked display value and a matching report destination. Leave unresolved outputs visibly open rather than filling them with estimates that look final. This approach supports a practical reporting handover: the calculation remains with its responsible process, while the client document faithfully communicates the accepted information. It also gives a future reviewer a short route from the reported value back to the evidence needed to understand it, without implying that the reporting software performed an independent technical approval.

Download the free workflow worksheetQuestions about this workflow
Why are formula cells blank after importing the workbook?
The importer does not execute formulas or use their saved results as newly checked values. It leaves those cells blank and warns you so you can obtain and enter reviewed results deliberately.
Can a saved spreadsheet result be out of date?
A stored result is not proof that the current intended inputs were recalculated. Confirm the calculation state and accepted output with the source owner.
Does checking the arithmetic authorize the reported disposition?
No. Arithmetic, method applicability and technical acceptance are different questions. The responsible process must address each applicable question.
What should I keep with a transferred result?
Keep the source and input version, calculation reference, reviewed value and unit, report destination, and the relevant review or unresolved action.
