Questions
Does it handle commas and line breaks inside fields?
Yes. Quoted fields are read and written as the CSV standard (RFC 4180) describes.
Are numbers kept as numbers?
Only if you choose Read numbers and true/false. Otherwise every value stays text, exactly as written.
Which delimiters does it know?
Comma, semicolon, tab and pipe. Detect picks the one the file uses.
Is my data uploaded?
No. It is converted inside your browser, and never leaves your device.
