Let’s say you have a column named “TicketNumber” of number type in your list. By default SharePoint formats it to show with commas. If your requirement is not to show those comma’s then here is a workaround.
Create another column of ‘Calculated’ column type and set the formula as follows:
=TEXT(Original_Number_Column_Name,“0”)
Ex:__=TEXT([TicketNumber],“0”)
And then use the calculated column in place of your original column for display purposes.
