CSV to JSON

Paste your CSV data (with headers in the first row) and click Convert. Each row becomes a JSON object, with column headers as keys. The output is a JSON array of objects.

Yes, the first row should be column headers. These become the JSON property names. If your CSV has no headers, add them manually before converting.

Numbers are automatically converted to numeric types, "true"/"false" become booleans, and empty cells become null. Everything else stays as a string.

Currently the tool expects comma-separated values. For TSV data, do a quick find-and-replace to change tabs to commas first, then paste into the converter.
