Frequently asked questions

When converting Excel to CSV, only the text data is preserved. Formatting, formulas, images, and charts will not be included in the CSV file.
Yes, absolutely. All processing is done locally in your browser. Your files are never uploaded to our servers.
CSV (Comma Separated Values) is a plain text format that stores tabular data. Unlike Excel, it does not support multiple sheets, cell formatting, or formulas.
You can, but the images and charts will be ignored. Only the text data in the cells will be extracted to the CSV file.
The default is comma (,), which is most common. Use semicolon (;) if your data contains many commas (like European number formats) or tab if required by specific software.
