FAQ

What file size can it handle?
Browsers can comfortably render 50,000+ rows, but the preview is virtualized at 200 rows for performance. Stats still run over the whole file.
Which delimiter is supported?
Comma, semicolon, tab, and pipe are auto-detected. You can override the choice in the controls.
Can I sort or filter inside the preview?
Yes — click column headers to sort. Use the CSV Sorter and CSV Filter tools for multi-key sort and regex filtering.
