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”

Extracted log entry fields

| Entry path | CSV column name | | ------------- | ------------- | | pageref | pageRef | | startedDateTime | startedDateTime | | request.method | requestMethod | | request.url | requestUrl | | request.httpVersion | requestHttpVersion | | request.headerSize | requestHeaderSize | | request.bodySize | requestBodySize | | response.status | responseStatus | | response.content.size | responseContentSize | | response.headers.name['content-type'] | responseContentType | | response.headers.name['content-length'] | responseContentType | | response.headers.name['cache-control'] | responseCacheControl | | timings.blocked | blocked | | timings.dns | dns | | timings.ssl | ssl | | timings.connect | connect | | timings.send | send | | timings.wait | wait | | timings.receive | receive | | time | time |

Note: Entries that don't match the above fields / paths are not included in the result CSV file

WIP

• Support TSV format
• Add flag for excluding columns from the result
• Output stats from the conversion e.g. # of requests, GET vs POST etc...
