Excel Model Checklist Before You Send It

Financial Modeling · Updated June 2026

The moment you send a model, it stops being yours. Whoever opens it judges your work by what they see in the first thirty seconds: a stray error, a forgotten cell on the wrong tab, a link prompt on open. This Excel model checklist catches those things before they reach the recipient.

Clear Every Error

No model should leave your hands showing #REF!, #DIV/0!, or #VALUE!. Even an error you know is harmless reads as carelessness to the recipient.

Resolve the root cause where you can rather than papering over it. If an error is genuinely expected, handle it deliberately rather than leaving raw red text on the sheet.

Use Find and Select then Go To Special to find errors, or scan each output sheet
Trace each error back to its cause
Fix the underlying formula or input
Re-check the totals after fixing, since one fix can reveal another

Settle the Inputs and Scenario

Confirm the model is set to the scenario you intend to send. It is easy to leave a stress-test toggle flipped or a sensitivity input at an extreme value.

Check that assumptions are current and that nothing is a leftover from a test run.

Scenario switches set to the intended case
No leftover test values in input cells
Dates and period headers current
Any draft notes to yourself removed

Tidy the View

Reset the cosmetic state. Return to the top-left of each sheet, set the active tab to the summary, and unhide anything the reader needs while hiding scratch work they do not.

A model that opens on cell A1 of the summary tab, zoomed sensibly, signals care before a single number is read.

Strip Stray External Links

Few things undermine trust faster than a link-update prompt the moment the recipient opens the file. It tells them the model depends on something they do not have.

Decide deliberately what should stay linked. For everything else, convert the links to values so the file is self-contained.

Find every cell that references another workbook
Decide which links must remain live
Convert the rest to static values
Re-open the file to confirm no update prompt appears

Remove Hidden Baggage

Workbooks carry metadata you may not want to share: author names, comments, hidden sheets, and tracked notes. A quick cleanup before sending keeps private context private.

This final pass turns a working file into something built for an outside reader.

Prepare to Share

Run a pre-send cleanup so the model opens clean, without stray prompts or hidden baggage following it out the door.

FAQ

What is the most important thing to check before sending a model?

That it opens clean: no visible errors and no external link update prompt. Those two things are the first impression. Everything else, from formatting to metadata, builds on a file that opens without a warning.

Should I always break external links before sending?

Not always. Some links are meant to stay live. The rule is to be deliberate: keep the links that belong and convert the rest to values so the recipient does not get a prompt for a file they cannot reach.

Why bother removing metadata?

Workbooks store author names, comments, and hidden sheets that can carry private context outside your organization. A cleanup pass before sending keeps internal notes and history from traveling with the file.
