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.

HAR to CSV Converter

Export every validated HAR request as a fixed spreadsheet-safe UTF-8 CSV summary.

Input
One valid .har file.
Output
A CSV of request URLs, methods, statuses, timings, sizes, cache, and compression fields.
Real limitations
CSV omits bodies, cookies, and the full nested HAR structure; it is a summary rather than a reversible conversion.
Privacy and data handling
one valid .har file is uploaded to a compatible Convertr worker only after you start the operation. Processing is automated, and temporary source and result files are deleted automatically after processing rather than retained as permanent storage.

How to use this tool

  1. Choose one valid .har file and wait for the page to validate it.
  2. Set the available output or inspection options, then start processing.
  3. Review the reported result and download a CSV of request URLs, methods, statuses, timings, sizes, cache, and compression fields before the temporary link expires.

Common failure modes

Malformed JSON, missing log entries, unsafe values, or a file outside the supported HAR structure causes validation to fail.

Useful example

Convert a browser network capture into one CSV row per request for timing analysis.
