CSV-to-JSON Workspace
Parse quoted CSV and preserve identifiers and leading zeros.
Quoted fields, escaped quotes and newlines are supported. Auto mode preserves leading zeros and integers beyond the safe numeric range. Maximum 10,000 rows. No files are uploaded.
How to use this tool
- Paste CSV or choose a supported file.
- Select the delimiter, headers and explicit type behaviour.
- Convert, inspect the preview or row error, then download the complete JSON.
Limits, privacy & troubleshooting
Maximum 2 MB and 10,000 rows. Headers must be unique and nonempty; inconsistent field counts and malformed quoting produce errors. String mode preserves values exactly. Auto mode keeps leading-zero identifiers and unsafe integers as strings.
Processing happens in your browser. Files and private inputs are not uploaded, added to page URLs or sent to analytics. Reset clears the current workspace. Downloads remain on your device until you delete them. Read the privacy policy.
