How it works
1
Paste your data
Drop in CSV with a header row, or an array of JSON objects.
2
Convert
CSV becomes JSON objects keyed by the header, and JSON becomes rows and columns.
3
Copy the result
Copy the converted data — nothing is uploaded.
Frequent questions
Does the CSV need a header row?
For CSV to JSON, yes — the first row’s column names become the keys of each JSON object.
How are commas and quotes inside values handled?
Standard CSV quoting is respected, so values wrapped in double quotes can safely contain commas, quotes and line breaks.
