If your forms pull in data from places like SharePoint lists, Excel Online, CSV, or JSON files, you can now make them even easier to test.
Previously, if you wanted your form to show different data while testing (for example, a “test” list instead of your real one), you had to create a separate test version of the form — which could cause confusion, multiple copies, and more work.
With Data Source Preview Environments, you can keep the same form, but have its data source point to one location while testing and a different location when live.
Why this is great:
No more duplicate forms — test and go live with the same form.
Built-in safety checks — ensures your test and live data are set up the same way to avoid surprises.
Better performance for regular users — they only sync the live data, not your test data, making forms load faster.
This feature is perfect for anyone who needs to safely test changes without touching live data.
