A grid UI component for any valid form of JSON

Usage no npm install needed!

<script type="module">
  import reactJsonGrid from '';


Simple React grid UI to display and edit any array of JSON data.

Explore the API with a live-example, API Playground here:

Most grid UI tools are either lacking in features, or require you to format your data in order to make it display in the grid. react-json-grid is designed to work with whatever data you already have handy, whether it's an array of JSON objects or simply a two-dimensional array of values.

Easiest API Possible

This component is built for line-of-business workhorse apps. Primarily, this was created to assist with banking applications that require large amounts of configuration and editing long lists of complex data.

Because it has to have near-XLS levels of user-friendliness coupled with repeated use throughout the application, it is designed to be as simple to use and configure as possible. For example, no matter what the format of data you've received, react-jason-grid can usually handle parsing and editing it. Just go to the live playground and give it a try.

Simple Usage

The API playground shows you the JSX you need to write in order to get the effect shown in the playground. In a nutshell, the API looks like this: = 
  [ {r:5,a:5,b:6,c:8,d:90},

  onChange={(x,y,objKey,value)=>{ data[y][objKey]=value; }}  

This project is inspired by react-data-grid.
