Har2CSV

Convert HTTP session HAR file logs into CSV format

This CLI tool provides you with an easy way to convert HAR file HTTP log entries into a flat CSV format to make it easier to analyze. The utility ignores fields that are not essential for analyzing requests/responses such as content and those that might carry private information such as cookies.

Usage

Install and run

Requires node v10.13.x or above

# Install

npm install har2csv -g

# Run

har2csv path/to/input.har path/to/output.csv

Generating a HAR file from a browser session

Example using Chrome:

Open the Dev Tools panel via Ctrl + Shift + i
Click the “Network” menu item on the top menu bar of the panel
The HTTP session is recorded by default, navigate to the pages / resources you're inspecting
Once ready to export the data, right-click anywhere on the list of items in the Network resource list and select “Save all as HAR with content”
