The pivot tables, already built
Exporting a capture to rows is the easy half. The half that takes the time is what everybody does next: group by host to find the third party that is costing a megabyte, group by content type to see whether the weight is images or JavaScript, sort by duration to find what stalled, filter to the failures. This workbook arrives with those four answers on their own sheets, and the raw rows still there underneath if you want to check the working.
- Summary, Requests, By host, By content type and Slowest
- Numbers stored as numbers, so your own formulas work
- Unmeasured sizes left blank instead of a -1 that breaks totals
- Tokens in URLs removed, so the workbook is safe to attach to a ticket
- Formula injection neutralised before anything reaches a cell
Want the plain rows for a script instead? Use HAR to CSV. Need the full capture with the credentials taken out? Use the HAR sanitizer.
About Converting HAR to XLSX
A HAR file is a JSON recording of everything a browser sent and received during a session, exported from the Network tab of its developer tools. It is the standard way to hand a web problem to someone who cannot reproduce it, and it captures headers, cookies, timings and response bodies in full. When you need to move away from HAR, the usual reason is simple: contains live session cookies and access tokens in plain text.
Converting your HAR data file to XLSX solves that. XLSX is the modern Microsoft Excel format — a ZIP of XML that stores multiple sheets, formulas, charts and formatting. It is the standard for business spreadsheets. In practice you gain formulas, charts and multiple sheets and open xml standard. PrivConvert runs the whole HAR-to-XLSX conversion in server memory and deletes your file the instant the XLSX is ready — nothing is stored, logged or reused.
When this conversion helps
- You need formulas, charts and multiple sheets

Tips for best results
- After converting, open the XLSX and skim the formatting — complex layouts occasionally need a small touch-up.
