# JSON Extractor Block **Advanced/Experimental**\ [Contact us](https://glif.app/contact) or [join Discord](https://glif.app/discord) to report issues Extract specific data value from JSON, for example from a WebFetcher or Text Generator block.

### JSON Data Paste your JSON into the "Value" input, or more usefully, use a variable to another block that returns JSON. ### Choose data to extract You can use a simple dot-notation syntax to fetch a specific field from a JSON response. Here's an example using this JSON: ```json [ { "id": "clgh1vxtu0011mo081dplq3xs", "name": "Heavy Metal Covers", "imageUrl": null, "description": "A new glif that performs some truly magical stuff" } ] ``` #### Output name This is the name of the variable that will hold the data. You can use the variable as `{blockname.outputname}` in other blocks. #### JSON Path Use the JSON Path `0.name` to extract the `name` property of the first object, "Heavy Metal Covers". Note that counting starts at 0 in arrays, so the first item is 0, the second is 1. At the moment, only text can be extracted from JSON. Let us know in Discord if you have other use cases. #### Fallback If the data isn't found in the JSON, this value will be used. This can also be a variable, if you want to live dangerously. ### Using the variables In another block, you can see the variables being available as `{json1.id}` and `{json1.name}`.
