FAQ
How are commas inside double quotes handled?
The CSV parser handles them correctly. In "a,b", the comma belongs to one cell; it is not a delimiter.
Which encoding is supported?
UTF-8 is assumed. If Excel renders garbled text, enable “Add UTF-8 BOM for Excel.”
Are multiline cells supported?
Yes. Multiline cells are supported. Large datasets may take longer, so converting a file and downloading the result is recommended.
Is data sent to a server?
No. Conversion runs entirely in your browser.
What if conversion fails?
The input delimiter may not be what you expect. Try Auto Detect or set it manually in Advanced options.
