I have a sheet I maintain where the core data comes from an excel export. The problem is this excel export is for the whole year and with no easy way to identify the new records since the last time the export was run, so when I copy and paste the records it creates duplicates.
Once the data is in the sheet, there are a few columns that are manually updated relating to these records.
My current process is to copy and paste all the records into my sheet. Then I have formula columns to identify duplicate records without the additional fields completed. This allows me to identify the records that can be deleted.
This process works for me, but I will likely be handing it over to someone. I curious if there are other potential solutions to consider that may work better.
Thanks!
