A slow page load is easier to argue about in a spreadsheet
The Network tab is built for watching requests as they happen, which is the wrong shape for the question you usually end up asking: what is actually taking the time? Once a capture is a table, sorting by duration takes one click, filtering to everything that returned an error takes another, and grouping by host or content type turns a wall of rows into a finding you can put in a ticket.
- One row per request, with timing and size ready to sort
- Tokens in URLs removed, so the export is safe to attach
- Formula injection neutralised for anyone opening it in Excel
- Headers and bodies deliberately excluded — this is a summary
Need the full capture, minus the credentials? Use the HAR sanitizer.
About Converting HAR to CSV
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 CSV solves that. CSV is a plain-text table format where each line is a row and commas separate columns. Its simplicity makes it the universal exchange format for data between spreadsheets, databases and code. In practice you gain readable by virtually every tool and tiny, plain-text files. PrivConvert runs the whole HAR-to-CSV conversion in server memory and deletes your file the instant the CSV is ready — nothing is stored, logged or reused.
When this conversion helps
- You need readable by virtually every tool
- You need tiny, plain-text files
- You need ideal for data import/export
- Sharing a HAR data file with someone whose software expects CSV
Tips for best results
- After converting, open the CSV and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several HAR files at once; each is processed privately and deleted immediately.
