SharePoint List - number column restrict values

Occasional Contributor

Hello All , 


We've SharePoint LIST column (Number) ,  1 decimal ,  Min Value is 1  , Max Value 3 

I want to restrict users from entering values other than these 5 below

  • 1
  • 1.5
  • 2
  • 2.5

is there any validation formula which can be used ? 


When data entered here its updating master LIST with number using FLOW 

So,  if I convert to choice column - not sure if Power Automate will pick value and convert to number when updating master LIST

@neeesz78 Use this column validation formula: 




Where [NumberCol] is name of your number column.
