Frequently asked questions
Does it handle quoted fields with commas inside?
Yes. The parser understands quoted fields, escaped quotes (""), and both LF and CRLF line endings, so values containing commas or newlines are preserved.
Can I use a tab or semicolon delimiter?
Yes. Pick Tab, Semicolon, Pipe, or define your own single character on the Options panel.
Array of objects vs array of arrays, which should I pick?
Array of objects uses the header row as keys (most APIs and JS code expects this). Array of arrays is just the raw rows, useful when you don't have headers or want positional data.
Is there a size limit?
Up to 2 MB of CSV per conversion, comfortably tens of thousands of rows. Split larger files into separate runs.
How long is the result kept?
The .json file is auto-deleted after 7 days. Re-download is available during that window via the secure link.
