Open a HAR file#

If you already have a HAR archive from another tool, you can open it in Web Debugger. You inspect it in the same way as a live recording.

Open a HAR or JSON file#

You can open a .har or .json file in two ways.

• Drag the file onto the empty drop zone in the centre of the Entries sub-tab.
• Select Choose File in the drop zone, then select a file from disk.

The file loads into the entries list. The tab title changes to HAR • <filename>, so you can find it among your other tabs.

Which sub-tabs work in static mode#

When you load a HAR file, the Entries, Network, and Rules sub-tabs all work against the loaded data. The recording toolbar disappears, because there is nothing to record. GraphDagger adds a Performance sub-tab for static files.

The following sub-tabs are not available for static HAR files, because they only act on live traffic:

• Scripting.
• Map Remote and Map Local.

Breakpoints stays in the sub-tab row, so you can write breakpoints in advance. Breakpoints only fire during a live recording.

Open a HAR file from Spotlight#

If you open a HAR file through Spotlight's Open with menu, the file loads into the active Web Debugger tab automatically. GraphDagger also adds the file to your recent items, so you can open it again from Spotlight later.

Open a HAR file without GraphDagger installed#

The read-only half of this workspace also runs in a browser as the free HAR viewer. It opens .har and .json captures with the same entries grid, detail panel, waterfall and Performance tab, and parses the file in the tab without uploading it. Binary formats such as Fiddler .saz and Proxyman archives still need the desktop app.
