Before sending an Excel file, take five minutes to review what the recipient will actually see.
Clear filters
Make sure important sheets are not accidentally filtered to a small subset of rows. If a filter is intentional, say so clearly.
Check hidden content
Review hidden sheets, hidden rows, hidden columns, and grouped sections. Remove anything the recipient should not receive.
Review formulas and links
Check for broken external links, formula errors, and formulas that depend on files the recipient cannot access.
Protect the right areas
If the file is a template or report, protect formulas and unlock input cells. Add instructions so people know where edits are expected.
Save a PDF when needed
If the file is for presentation rather than editing, send a PDF version too. That preserves the view you intended.
Go deeper with this skill
Prepare a workbook so other people can review it without breaking formulas or guessing what changed. For this article, the goal is to practice: Check formulas, hidden sheets, filters, links, print settings, and sensitive data before sharing a workbook.
Practice workbook setup
Use a copy of a workbook that contains inputs, formulas, and at least one summary sheet.
Practice workflow
- Mark input cells, formula cells, and output cells with a consistent visual system.
- Add comments or notes only where a decision needs context.
- Protect formula-heavy areas after confirming reviewers can still edit the intended cells.
- Save a dated review copy before sending or sharing the workbook.
Quality checks
- Reviewers know where to enter feedback or new values.
- Important formulas are protected from accidental edits.
- The workbook has a clear version or date marker.
Common mistakes
- Sending a workbook with hidden sheets or stale filters still active.
- Using comments as a replacement for clear labels.
- Sharing before checking links, formulas, and external references.
Next actions
- Create a review checklist tab and reuse it for future workbooks.
- Test the file by opening it from the same link or attachment a reviewer will use.
Formula focus: even if this workflow is not formula-heavy, add one check cell that confirms the final output still matches the source data.
