Frequently asked questions
How are quoted fields handled?
The parser follows RFC 4180 — commas, quotes and line breaks inside double-quoted values are preserved correctly.
Which delimiters are supported?
Comma, semicolon and tab are auto-detected from your data, so exports from Excel, Google Sheets and databases all work.
Is there a file size limit?
Files up to several megabytes convert instantly. Everything runs in-memory in your browser — nothing is uploaded.
