Frequently Asked Questions
What input format does this tool expect?
A CSV file where the first row contains column headers. Each subsequent row becomes a JSON object with those keys.
Are quoted fields with commas handled correctly?
Yes. The CSV parser handles RFC 4180 quoting, so fields containing commas or newlines inside double quotes are parsed correctly.
Is my data uploaded to a server?
No. Conversion runs entirely in your browser using JavaScript.
Example input/output
Input: name,age
Ada,30
Bob,25
Output: [{"name":"Ada","age":"30"},{"name":"Bob","age":"25"}]
How it works
This tool parses the CSV using a comma delimiter. The first line's values become object keys; subsequent lines produce one object per row. All processing runs in your browser.
