CSV to JSON Converter
Paste delimited data and get clean JSON out. Quoted fields, embedded commas and embedded newlines are parsed properly rather than split naively.
How to use it
- Paste your CSV, TSV or semicolon-delimited data.
- Leave the delimiter on Auto-detect, or set it explicitly if the guess is wrong.
- Press Convert and copy the JSON.
Why it stays private
CSV exports from a business system usually contain real customer or financial records. Parsing them locally means the whole file never has to leave the machine it is already on.
Questions
Does it handle quoted fields containing commas?
Yes. A proper parser is used, so "Smith, John",42 is correctly read as two fields rather than three, and doubled quotes inside a quoted field are unescaped as a single quote.
What happens if my rows have different numbers of columns?
Short rows produce null-free empty strings for the missing header columns, and extra values beyond the header are dropped. This mirrors what most spreadsheet exports do and keeps the output rectangular.
Can I convert JSON back to CSV?
Not with this tool yet. It converts in one direction only.
