# Parsers

Certain Juttle [adapters](../index.md) support `-format` option which allows you to read in data in various formats:

* [json](https://tools.ietf.org/html/rfc7159)
* [jsonl](http://jsonlines.org/)
* [csv](https://tools.ietf.org/html/rfc4180)
* grok

Parsing of JSON, JSONL and CSV formats is straightforward; grok is documented [here](grok.md).
