Convert an Excel Sheet to CSV
Open an XLSX or XLS workbook, inspect a worksheet, and export it locally as CSV.
Export one worksheet without uploading the workbook
FreNiMi reads the workbook locally, lists its worksheet names, and previews a limited portion of the selected sheet. The CSV download contains that complete worksheet using the chosen delimiter and line endings.
Excel conversion questions
Can CSV preserve formulas and formatting?
No. CSV stores displayed cell values as plain rows and columns. It does not preserve formulas, colors, charts, multiple worksheets, or merged-cell formatting.
Which worksheet is converted?
Select one worksheet from the list. Each CSV download represents one worksheet.
Why include the UTF-8 marker?
It helps many spreadsheet applications recognize accented and non-Latin characters correctly.
