Add a json LSP to your editor, or use VS code which includes it natively: https://www.npmjs.com/package/vscode-json-languageserver Configure a json schema for the document you're editing and suddenly you get suggestions, validation, etc. as you type. It's pretty magical.

There's one for yaml too that works well in my experience: https://github.com/redhat-developer/yaml-language-server
