Frequently asked questions

Do I need to create an account?

No. Just open the site, upload your CSV, and start exploring. There is nothing to sign up for.

What browsers can I use to view CSV files online?

Large CSV Viewer works in Chrome, Firefox, Safari, and Edge. Any modern browser released in the last four years will work well.

Can I view a CSV file on my phone?

Yes. The interface is responsive and works on mobile browsers, though a desktop browser gives the best experience for wide tables.

What if my CSV has a non-standard delimiter?

The viewer auto-detects comma, semicolon, and tab delimiters. If your file uses a different separator, the columns may not parse correctly.

Is there a row limit when viewing online?

No row limit. Files with millions of rows are handled via server-side pagination — you navigate your data without any truncation.
