Tips for best results

Active sheet only

CSV is a single-table format. Only the sheet that was active when you saved the .xlsx gets exported. For multi-sheet workbooks, save each sheet as a separate file first or export them one at a time.

Values, not formulas

If a cell shows =SUM(A1:A10), the CSV captures the resulting number — the formula itself is lost. Keep the .xlsx archived if you need the logic later.

Merged cells lose context

Merged cells collapse into the top-left value; the other cells become empty. Unmerge before export if your downstream tool needs a dense, complete data grid.

Frequently asked questions

Which sheet is exported?

The first (active) sheet is exported. Multi-sheet export is not currently supported.

Will formulas be exported?

No — the calculated values are exported, not the underlying formulas.

Are merged cells handled correctly?

Merged cells export the value in the top-left cell of the merged range. Other cells in the merge appear empty.

What encoding is used?

UTF-8 encoding, compatible with Excel, Google Sheets and most data tools.
