Sharepoint Column Name Issue

GovindPrajapat Did you create a new SharePoint list by importing the excel/csv file?

SharePoint creates columns with internal names like field_1, field_2 etc. in case if you create new list by importing the excel file.

Unfortunately, you cannot change the names for the column after creating the columns/list. If you rename/change the column names, it will only change the display name of columns and not internal names.

Hence, you see the column names like field_1, field_2, etc. in the Power Apps. Check: How to find the Internal name of columns in SharePoint Online? 

To avoid this, you might need to create a new list using "Blank list" option with proper names (check guidelines for names in above link) and then import the data from excel using Power automate flow.
