Frequently Asked Questions

Can I open files with semicolons or tabs?

Yes! The tool automatically senses the delimiter (comma, semicolon, tab, or pipe) from the first line and renders the columns accordingly.

Does it handle quoted fields containing commas?

Yes! Full RFC 4180 parsing is supported, ensuring values like "San Francisco, CA" stay in one unified cell.

Is there a row limitation?

Because it renders efficiently with virtual pagination (10 to 100 rows per page), it easily handles datasets with tens of thousands of rows smoothly.
