Usage

In practice, Lansky files are used directly inside our workflows.
When designing a workflow, a developer or configurator creates a computer and attaches the .xlsx calculator file to it.

When a request related to this workflow is updated — for example, when an input field changes — the associated Lansky calculator is automatically executed.
The process follows three main steps:

1. Data injection — The engine injects all relevant request data into the input (and multi) sheet.
2. Execution — Excel formulas inside the Lansky file are evaluated.
3. Extraction — The resulting data from the output sheet is read and converted back into structured JSON.

The generated output is then injected back into the request’s data, making it available and reusable across the entire workflow.
In short, the Lansky acts as a live computation module inside the application — automatically triggered and keeping the data consistent with every change.
