Duplicate Check (Form to Data Source) - Thoughts/Ideas

(0) ShareShare
ReportReport
Posted on by 240

Hello,

I am hoping for ideas, on how best to check for duplicates of a submitted form and what is possible to set up to avoid and stop this from happening.

 

Basically i want something that doesn't allow a form to be submitted if an identical/partial match of an already existing record is already present within the data source (which happens to be an excel spreadsheet).

 

I had the idea of maybe a check to see if some information is already present so a unique identifier like an employee number paired with a date field being recognised as already exisiting on the data source. Creating the duplicate flag.

 

Open to any idea/experience that anyone has with this though and the best way to prevent duplicates.

 

Thank you!

Chris

    Hello @Appy1 

     

    I would suggest you use Power Automate.

     

    When a form is submitted it goes to an automated flow. In that automated flow, you use the form inputs like maybe Email to check if a record with email exists in a database.

     

    After that, if there is a result, you can create an action on maybe to tell that person that a prior submission has been made and not add it to your data store.
