Description

Does this issue occur when all extensions are disabled?: Yes

  • VS Code Version: 1.94.0-insider (Universal)
  • OS Version: Darwin x64 23.6.0

Steps to Reproduce:

  1. Enable editor.formatOnPaste and editor.formatOnSave and set editor.defaultFormatter to "vscode.json-language-features" for json files.
  2. Paste a line into a json file that is not indented correctly.

Result: The pasted line is not formatted on paste, but is formatted once the file is saved. If the same steps are tried with another file type such as TypeScript the pasted line is formatted as expected.

Contributor guide

Research direction
Trace the format on paste mechanism for JSON files in VS Code's built in JSON language extension. Look at the 'vscode json languageservice' or related formatter code to see why format on paste is not triggered.
