Auto-number records (invoice numbers, IDs)
Updated Jun 25, 2026
SheetApps can assign a running number to each new record so you don't have to manually assign one in the form.
How to auto-number records?
- In your Rules_ sheet, give the field an auto (or autogen) rule type.
- Open the app and click Change app to upload the workbook.
- New records now get the next number automatically; the field is read-only in the form.
Good to know
- Auto-numbering is great for invoice numbers, ticket IDs and asset tags.
- Combine it with a key rule type so each record stays uniquely identifiable on import.
- Assign rule types "auto" and "key" to the relevant field
- In Rules_ sheet, these entries will be made in different rows
