# Can Claude update an Excel workbook without breaking its formulas?

Has anyone used Claude to make small changes to an existing Excel workbook—for example, updating a few input values or adding a column—while keeping the formulas and cell references intact?

I’m less concerned about generating a new spreadsheet from scratch than preserving the workbook I already use: formulas, formatting, and links between sheets. What kinds of edits have worked reliably for you, and what did you have to check manually afterward?
