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...
