FAQ
Why convert CSV to XLS?
CSV files are plain text — they don't support formatting, formulas, or multiple sheets. Converting to XLS lets you open data in Excel with full spreadsheet functionality.
Is my data safe?
Yes. Conversion uses the SheetJS library running entirely in your browser. No data is uploaded anywhere.
Is there a file size limit?
No hard limit, but files over 50MB may be slow in the browser. For very large datasets, consider using Excel directly.
