FAQ
How are commas inside double quotes handled?
A CSV parser interprets them correctly. In "a,b", the comma is part of one cell, 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. For large datasets, processing may take longer, so file conversion plus download is recommended.
Is data sent to a server?
No. Conversion is fully local in your browser.
What if conversion fails?
The input delimiter may not match your expectation. Try Auto Detect or set the input delimiter manually in Advanced options.
