What format does Google Chrome Developer Tools save data as?

Question

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:

Is there any way to open this directly with Chrome? – Pacerier Dec 29 '14 at 08:32
@Pacerier Yes. It's just a JSON file. – Cees Timmerman Jul 10 '15 at 08:11
This has always baffled me - why does Chrome allow you to save HAR files but not open them? – Kyle Pittman Jul 21 '16 at 18:59

.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.)
