Data Transformer is a desktop app for converting between common data formats.
Need to send a JSON or YAML file when your data is currently in a spreadsheet? Need to load XML or JSON into SQL or analytics workflows without writing one-off scripts? Data Transformer does exactly that.
It is built for fast, reliable conversion between structured formats. The interface is simple, with enough control for real-world transformation tasks.
Unlike many web converters, Data Transformer processes files locally. On macOS, this is reinforced by Apple’s sandbox permissions, which you can review before installation. Your data stays on your computer.
