사용 방법
CSV looks simple but is full of edge cases — quoted fields, commas inside quotes, line breaks inside cells. This uses a proper RFC 4180 parser so those all work, entirely in your browser.
- 1You paste CSV or drop a fileThe delimiter (comma, semicolon, tab, or pipe) is auto-detected, or you can set it manually. Nothing is uploaded.
- 2It's parsed correctlyQuoted fields, escaped quotes (""), and delimiters/newlines inside quotes are all handled per the CSV spec.
- 3You choose the shapeWith a header row, each line becomes an object keyed by the headers; without, an array of arrays. Optionally convert numbers and booleans to real types.
- 4Copy or download JSONGet clean, indented JSON ready for your code.
CSVs frequently hold contacts, transactions, and other personal data. Parsing happens entirely on your device — none of it is uploaded.
