Is there a way to tell specify the files to format (not the ones to ignore!)

I know of prettier.ignorePath, prettier.disableLanguages and the .prettierignore file. But they all exclude some files.

I want to be able to tell the Prettier extension to only format .ts and .json files. Is this possible?

["javascript","javascriptreact","typescript","typescriptreact","json","jsonc","css","postcss","less","scss","graphql","markdown","vue"] these are all supported languages.

You will have to add every languages you don’t want in prettier.disableLanguages

In @electrotype 's example: prettier.disableLanguages: ["javascript","javascriptreact","typescriptreact","css","postcss","less","scss","graphql","markdown","vue"] ie everything but the ones you want : "typescript","json","jsonc"

It’s not possible to add a language. HTML is not supported by prettier yet

You can also do this in workspace settings.json:

{
    "editor.formatOnPaste": true,
    "editor.formatOnSave": true,
    "editor.formatOnType": true,
    "[markdown]": {
        "editor.formatOnPaste": false,
        "editor.formatOnSave": false,
        "editor.formatOnType": false
    }
}
