Convert CSV data into a JSON array of objects. Runs entirely in your browser.

What CSV format is expected?
The first row must be column headers. Each following row becomes a JSON object in an array. Comma-, tab-, and semicolon-separated files are auto-detected. Quoted fields are supported.
Are numbers converted automatically?
Empty cells become empty strings. TRUE, FALSE, and NULL are converted to JSON booleans/null. Other values stay as strings.
Is my data private?
Yes. The conversion runs entirely in your browser — nothing is uploaded.
