 # outputJsonSync(file, object, [options])
 
 Almost the same as [`writeJsonSync`](writeJson-sync.md), except that if the directory does not exist, it's created.
-`options` are what you'd pass to [`jsonFile.writeFileSync()`](https://github.com/jprichardson/node-jsonfile#writefilesyncfilename-obj-options).
 
 **Alias:** `outputJSONSync()`
 
 - `file` `<String>`
 - `object` `<Object>`
 - `options` `<Object>`
+  - `spaces` `<Number|String>` Number of spaces to indent; or a string to use for indentation (i.e. pass `'\t'` for tab indentation). See [the docs](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#The_space_argument) for more info.
