CSV to JSON Converter: a practical guide
Convert comma-separated records into a structured JSON array.
Open CSV to JSON ConverterWhen this is useful
CSV is a row-and-column format often used for exports and spreadsheet handoffs. Turning it into JSON is useful when an API, fixture, or script expects named fields. A reliable conversion needs a clear header row and a parser that understands quoted commas, embedded newlines, and doubled quotes.
A reliable workflow
Paste the complete CSV including its header and convert it. Each data row becomes an object keyed by the headers. This tool keeps values as strings, so a code such as 0012 remains 0012 rather than becoming the number 12. Headers must be nonempty and unique; inconsistent row lengths produce a validation error.
Example input: name,city Ibrahim,Karachi
What to check before you finish
A comma is the delimiter in this tool. Tab-separated and semicolon-delimited files need a separate conversion first. Review dates, blank values, and whitespace according to your schema before sending the JSON to an API. The browser tool limits source text to 1 MB to keep memory use predictable.
