CSV ↔ JSON Converter
Convert a CSV table with headers into an array of JSON objects and back. Quoted values with commas are supported. Processing is fully local — safe for real data.
Frequently asked questions
What CSV format is expected?
First row = column headers, comma separator, values containing commas wrapped in double quotes.
What about nested JSON?
A flat array of objects converts cleanly to CSV; flatten nested structures first.
