@502647092 I believe you’ve already opened a similar issue #6758. I think it’d be better to continue the discussion on the past issue.

To answer your question:

1. Formatting is supported by the @theia/json extension, and it works correctly from sources.
   If it does not work, it is likely fixed with resolutions as you mentioned [json] JSON file can't format #6758 (comment).
2. Formatting from the vscode-builtin-json-language-features builtin is not yet supported (there is compatibility still missing from the framework). Moreover, there are other compatibility issues with the extension, for example Implement SelectionRange and SelectionRangeProvider #6623, which is part of the reason why it has yet to be used in this repo to replace @theia/json.

But we should start working on deprecating @theia/json and switching to VS Code counterpart.
