Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your JSON files into STP without GIS software - all files processed on your PC for maximum privacy and speed.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see JSON data has GIS software. reaConverter renders it to STP for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to STP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.
