Excel y CSV

Q: Which spreadsheet formats are supported?

The Excel tools support modern OpenXML workbooks (.xlsx), legacy spreadsheets (.xls), and delimited text files (.csv).

Q: Is my proprietary financial data secure?

Yes. Tabular data parsing executes locally in your browser memory via SheetJS with no data transmission to external servers.

Q: Can I open exported workbooks in Google Sheets or LibreOffice?

Yes. Generated .xlsx files comply with standard OpenXML specifications and open cleanly in Microsoft Excel, Google Sheets, Apple Numbers, and LibreOffice Calc.

Q: How are formulas handled when splitting or merging?

Calculated formula values and data types are preserved. Internal references to external sheets in split files convert to static calculated values.
