JSON support hasn't yet been release, and this is not a valid JavaScript statement (it's a valid javascript expression). I'm working on the next release, so please wait a bit more :)

@vjeux
Oh, since the Readme listed a json parser I assumed it supported json. Awesome work, looking forward to the next releases!

Interestingly, this error pops up with prettier@1.11.1 configured with the "typescript" parser.

Config file:

{
  "useTabs": false,
  "printWidth": 80,
  "tabWidth": 2,
  "semi": true,
  "singleQuote": true,
  "trailingComma": "all",
  "bracketSpacing": true,
  "jsxBracketSameLine": false,
  "parser": "typescript"
}

See also: prettier/pretty-quick#23 (comment)

Removing the "parser": "typescript" line and using default fixes the issue.

@jbmusso configuring prettier with parser in your prettierrc/package.json will force prettier to use that parser for all files by default, including JSON. That's why it errors. Prettier autodetects which parser to use based on file extension so in most cases you do not need to set the parser.

Experiencing this error in v1.13.x:
It was working however in v1.11.x, both are using the bablyon parser

@vjeux I believe there is a breaking change between these versions

edit: also tested v1.12 where it is working

@coleturner Prettier 1.13 fixed a bug where your parser choice in your config file was incorrectly ignored for some files (see #4633). The babylon cannot parse many JSON files because they are not valid JS programs. Some people have run into this error because they added parser: "babylon" at the top level of their .prettierrc, which is a really bad idea. See #4642 and #4638. It could be that all you need to do is removing parser: "babylon" from your .prettierrc and you should be all set. Hope this helps.

Aha I see, this is an edge case then, please ignore :P

I'm getting this error with no parser specified. My override was also ignored.

overrides:
  - files: "*.json"
    options:
      parser: json

@texastoland Can you open a new issue and fill out the formatting template?
