3. ✨ Enable Smart Match for Field Matching
🧪 Test your form actions here: https://multifield-copycat.com/demo
- By default, fields are pasted in the order they were copied. This ensures exactly the same sequence is preserved, which is useful when the destination form has the same layout as the source.
- Enable Smart Match before pasting allows MultiField CopyCat to try to match fields by text automatically. This helps paste form data correctly even when fields are in a different order.
- How to enable Smart Match:
- Open the popup before pasting → Click Enable Smart Match
- Perform pasting action as usual
- Copied data will be pasted into fields that are similar
- Once enabled, Smart Match will remain active for future pasting actions. You can toggle it on or off anytime to suit your needs
We're continuously improving Smart Match accuracy (no AI — just one developer's brain!). Feel free to contact us if you encounter edge cases so we can improve and provide better coverage for everyone.
