CSV to JSON Converter
Convert CSV (with a header row) into a clean JSON array of objects.
JSON will appear here.
Paste CSV where the first row is the header to get a JSON array of objects keyed by column name. Quoted fields, embedded commas and quoted newlines are parsed correctly, and obvious numbers and booleans are typed automatically. The conversion happens locally in your browser.
How to use the CSV to JSON Converter
- Paste CSV with a header row into the input box.

- Copy the JSON array for your code or API.
Frequently asked questions
Does the first row need to be a header?
Yes. The first CSV row becomes the object keys; each following row becomes one object.
Are numbers converted to real numbers?
Yes. Cells that look like numbers or true/false are typed accordingly; everything else stays a string.
Does it handle quoted fields with commas?
Yes. The parser honours double-quoted fields, escaped quotes ("") and newlines inside quotes.
