FAQ

Does Delete Excel Sheets upload my workbook?

No. Processing happens in your browser. The page does not send workbook contents to a server.

Will Delete Excel Sheets overwrite the original file?

No. It creates a separate download, so your selected source file remains unchanged.

Can I delete the only worksheet in a workbook?

No. An XLSX workbook needs at least one visible worksheet, so the tool stops when only one sheet exists.

Are formulas recalculated like desktop Excel?

No. Formula text can be preserved or inspected, but this browser tool is not Microsoft Excel's calculation engine.

What size workbook should I use?

For dependable browser performance, use files under 40 MB and worksheets below 750,000 cells. Split larger files first.
