Frequently asked questions

Does this support quoted fields with commas inside them?

Not currently — this handles standard comma-separated values without embedded commas in quotes.

What if my CSV uses semicolons instead of commas?

Replace semicolons with commas first, or this conversion won't split columns correctly.

Is there a row limit?

No hard limit, though very large files will take longer since everything runs in your browser.
