Help

When should I use Excel to CSV conversion?

Use it when you need to convert Excel-managed order records, member lists, product data, or statistics tables into CSV format for upload to another program or system.

How do I convert files with multiple sheets?

After uploading an Excel file, the sheet list is displayed. Since CSV usually stores data from one sheet, select the sheet you need and download each sheet separately as CSV.

Are Excel styles preserved when saving as CSV?

CSV is a text-based data format, so styles such as colors, merged cells, fonts, borders, and formula display formats are not preserved. The converted result stores cell values from the selected sheet separated by the chosen delimiter.

Is the file uploaded to the server?

This utility reads Excel files and generates CSV data in the browser. In normal use, uploaded files are not stored on the server.
