Displays formatted JSON data with syntax highlighting, expandable/collapsible objects and arrays, and customization options for visual appearance. Integrates seamlessly into Compose UI for enhanced JSON visualization.
JsonTree is a Compose Multiplatform library to display JSON data in Compose with syntax highlighting and more.
JsonTree is an Compose Multiplatform library to display formatted JSON data in Compose. Users can expand/collapse objects and arrays, which can also display additional info like item counts and item indices for arrays. JsonTree offers several customizations for visual appearance like syntax highlighting, text style and icons.
See maven tag at the top for the latest version.

Add the sonatype snapshot repository to your gradle setup and add the dependency from above. See maven tag at the top for the latest snapshot version.
maven { url = uri("https://central.sonatype.com/repository/maven-snapshots/") }
Add JsonTree to your Compose UI and customize it with the following options. Get started by only providing your JSON data and a Composable for the initial loading.
JsonTree(
json = "{ \"key\": \"value\" }",
onLoading = { Text(text = "Loading...") }
)
For more customization, use the following parameter.
JsonTree can be searched for keys and values by using the searchState parameter. The SearchState provides the following data about the current results. For an example on how to implement a search UI see the sample here.
query - The string which should be searched in the JsonTreetotalResults - The total count of results for the queryselectedResultIndex - The index of the currently selected resultselectedResultListIndex - The index of the list item in which the selected result is locatedThis repository is open for contributions. However, PRs might get rejected if they don't fit the current structure or goals of the project. If you want to contribute, it might be a good idea to open a issue to describe your idea before spending a lot of time implementing it.
