Frequently asked questions

Will number and date formatting be applied automatically?

Values are imported as their raw text or numeric form. Apply specific formatting in Excel after importing if you need custom number or date display formats.

What delimiter does the CSV need to use?

Standard comma-separated CSV is expected. If your file uses a different delimiter, such as semicolons, results may not parse as separate columns correctly.

Can I convert a very large CSV file?

Yes, though very large files (100,000+ rows) may take longer to process since everything runs in your browser.
