I am using Google chrome's developer tools to inspect the timeline of some requests. There is the option of storing them as a .HAR file, but I could not find anything that opens it. In a browser, it looks like a simple text file.
Does anybody know how to save Developer Tool's data in a suitable format or how to open .HAR files?
The HTTP Archive format (HAR) format is intended to be a format for sharing HTTP data across tools. Although there are a bunch of tools that support HAR & allow exporting, only a few among those appear to allow import:
.har seems to be an HTTP Archive Spec file. You can use HTTP Watch to open such files. FWIW those are JSON files
Starting in Chrome 62 you can simply:
Drag and drop a HAR file into the Network panel to import it.
(From the release notes.)
