CSV to JSON Converter
Convert CSV data to JSON.
How CSV to JSON conversion works
Step 1
Paste your CSV
Add CSV data that includes a header row into the input box.
Step 2
Convert to JSON
The tool reads the header row as property names and turns each following row into a JSON object, producing a JSON array.
Step 3
Copy or download
Copy the JSON output for use in your code, API or configuration file.
Frequently asked questions
Does the converter require a header row?
Yes. The first row is treated as column names, and those names become the keys in each JSON object.
What happens with extra or missing values in a row?
If a row has fewer values than there are headers, the missing fields are left empty in the resulting JSON object.
Is my CSV data uploaded to a server?
No. CSV to JSON conversion happens entirely locally in your browser.
