Why this tool is useful
Move a recorded network trace into a spreadsheet or data-analysis workflow without copying cookies, headers, bodies or query-string values into the tabular export.

Private HAR Request Summary to CSV
Export one bounded CSV row per HAR request with timestamp, method, host, sanitized path, status, MIME type, duration, wait, receive and byte measurements without query values.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
How it works
The local parser validates HAR structure, derives conservative timing and size columns, masks token-like path segments, applies RFC-style CSV escaping and emits a UTF-8 file.
Practical example
Select a 600-request page-load HAR and download har-requests.csv to sort endpoints by wait time or response size while keeping credential-bearing fields out of the sheet.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
