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.
