harextract
Browser-based HAR extraction tool.
You can use it online if you don’t want to download it.
All you need is harextract.html – it’s completely self-contained and doesn’t require any online resources.
Open the page in a browser and use the file chooser button on the page to load a HAR file.
From there you can save individual files, and also save the entire collection as a ZIP file:
It is extremely basic right now but may evolve over time.
Bugs
Probably a ton. Written quickly and only tested on Chrome for Windows. Report them on the issues page.
