HAR to CSV Converter

Inspect a HAR 1.2 file and export a complete fixed-schema request summary as spreadsheet-safe UTF-8 CSV.

Choose an uncompressed .har or .json file up to 1 GB. HAR files can contain active session secrets; upload only files you are authorized to process.

Safety and interpretation limits

Convertr validates and reads the uploaded JSON only. It never fetches or replays a recorded URL, resolves DNS, executes scripts, renders response bodies, creates cURL commands, or acts as a network proxy.

Browser timing fields can be missing, negative, cached, connection-reused, or vendor-specific. Summaries preserve those semantics and exclude unavailable phases from averages.
