New JSON Viewer is changing the JSON serialized value for some numbers

[shawnwildermuth]

When using Edge for testing of an API, the JSON Viewer is changing the underlying JSON. See below:

I'd prefer to just turn off the view for now (since I am using extensions that do this, but they aren't enabled when the JSON Viewer is on).

Thanks for filing this issue. I'm having some difficulties reproducing the problem though. Here is what I tried:

1. Open a new tab in Microsoft Edge.
2. Enter the following URL in the address bar: data:text/json,[{"id": 1636, "price": 43.00}].
3. Press Enter.

Here is the result:

I'm not seeing the change to {value: "43.00n", "type": "Big Number"} like you do.

@shawnwildermuth would you be able to provide a URL or JSON file for us to reproduce the issue?
Also, what's your Edge version?

In terms of disabling the JSON Viewer, you can do so by following these steps:

1. Open a new tab and go to edge://flags
2. In the search box at the top of the flags page, search for json viewer
3. Change the flag to Disabled and then restart Edge.

So, I am seeing the same thing you are (because the JSON Viewer isn't being enabled for this query:

But when I go to an URL (instead of a data block or even a local file), the JSON Viewer is used:

When I open the edge://flags, I don't see a JSON Viewer.

I seem to have the latest version (though I am not using a preview of Windows):

On this screenshot:

the toolbar which you point to doesn't belong to the official Microsoft Edge JSON viewer. I don't know where it comes from, but it isn't our JSON viewer. Do you have an extension installed that handles JSON responses? I'm wondering if the Edge JSON viewer and a potential extension are competing to display JSON responses.

I didn't think so. Let me look. That would explain a lot.

So sorry for wasting your time. This was JSON Beatify extension that I thought I disabled. I mistakenly thought the icon here disabled, not just hid from the tool bar:

Totally a problem between the chair and the keyboard.

Thanks for checking and reporting.
