'\x00' is the null character, which is illegal in JsonTools.

The following JSON cannot be pretty-printed:

{"my_key_name":"Test\u0000"}

It can be formatted in JSONViewer: https://github.com/NPP-JSONViewer/JSON-Viewer

I verified it in the following website: https://jsonformatter.curiousconcept.com/#

I made a conscious decision when designing JsonTools to not allow parsing of \x00 or \u0000 because JsonTools can't output literal NUL characters into Notepad++ due to strings that JsonTools sends to Notepad++ being treated as NUL-terminated C-strings. So this is not a bug per se but an implementation decision on my part.

However, I've decided that this was not a good decision, and I plan to fix this issue this weekend. Because JsonTools formats NUL characters as \u0000 and not a literal NUL character, the aforementioned limitation doesn't matter, and I was wrong to have this restriction. I'll let you know when I commit my fix, so that you can test it.

I believe this issue is fixed by this commit. If you want to test out this commit, follow these instructions for downloading unreleased versions.

As noted in the commit message for that commit, JsonTools has a number of issues surrounding NUL characters that I am completely incapable of resolving, because they are rooted in the fundamental ways that it interfaces with Notepad++. That said, almost all of the JsonTools plugin commands from that commit onward should correctly handle your JSON containing \x00 or \u0000.

Thanks man. That was fast. I'll check it out in 2 days when I get back to work. I think your extension is better than JsonViewer thanks to so many features. Well done.

Looks like the fix works for my use case. Thanks!

Glad I could help! As usual, I'll close this issue shortly after the first release with the fix incorporated is available via the Plugins Admin.

JsonTools v8.3.1 is the first official release with this fix implemented. Once a version of Notepad++ (hopefully 8.7.5 or 8.7.6) with a plugin list that includes JsonTools v8.3.1 is live for about a week with no reports of a recurrence, I'll close this issue.

NOTE: This comment previously recommended upgrading to v8.3, but v8.3.1 fixes an easily replicated crash bug.
