Get started with Kotlin DataFrame in Kotlin Notebook
Kotlin Notebook is an interactive environment
integrated into IntelliJ IDEA, designed for fast, iterative, and visual data exploration with Kotlin.
The Kotlin Notebook plugin transforms IntelliJ IDEA into a powerful data science workspace,
combining Kotlin’s strong language features with live code execution, interactive data exploration, and rich visualizations
It’s perfect for working with Kotlin DataFrame — letting you write code, view results instantly, and refine your analysis step by step.
tip
Before version 2025.1, Kotlin Notebook is unavailable in IntelliJ IDEA Community Edition and not bundled in IntelliJ IDEA Ultimate Edition by default.
Make sure the Kotlin Notebook plugin is enabled.
Open an IntelliJ IDEA project (either new or existing).
In the project view, create a new Kotlin Notebook file:
Press or right-click the project tree, then select Kotlin Notebook.
For more details, see
Get started with Kotlin Notebook
on the official Kotlin Documentation website.
In the new notebook file, execute the following cell to add the Kotlin DataFrame library:
%use dataframeThis will load all necessary dependencies, add required imports, and enable rich DataFrame rendering in the notebook.
By default, if no version is specified, the version bundled with the notebook kernel is used.
You can explicitly define the version you want:
%use dataframe(1.0.0)Or use the latest stable version of Kotlin DataFrame (specified in Kotlin Jupyter descriptors):
%useLatestDescriptors
%use dataframeLet’s create your first Kotlin DataFrame in the notebook — a simple "Hello, World!" style example:
val df = dataFrameOf(
"name" to listOf("Alice", "Bob"),
"age" to listOf(25, 30)
)To display it, run a cell with the DataFrame variable in the last line (or simply a cell containing the variable):
dfYou will see the content of this DataFrame rendered as an interactive table directly in the cell output:
