How to use this tool
Paste your CSV data or open a local CSV file. Choose whether the first row contains headers, then review the live JSON output. Copy or download the converted file.
Quick steps
- Paste CSV text or import a local CSV file.
- Choose whether row one contains headers, and select objects or arrays.
- Preview the converted records, then copy or download JSON.
Practical tip
Fields wrapped in double quotes can include commas or line breaks. Duplicate headers are rejected in object mode so no data is silently lost; array mode preserves all columns.
Common questions
Does the converter support quoted commas?
Yes. It parses quoted fields, doubled quotation marks, commas and line breaks in CSV records.
Can I convert CSV with no header row?
Yes. Turn off First row contains headers to create numbered object keys or select array output.
Are my CSV files uploaded?
No. Files and text are processed locally inside your browser.
