Here is a technique that I learned from @Jeff_Hager. You will need a RowID column in your sheet.
- Create a self-relation linking the company name to itself. This should be a single relation (call this
rel-self
) - Create a Lookup column to fetch the RowID from that relation (call this
lk-unique-id
) - Finally, create an if-then-else column: If RowId is lk-unique-id, then true. Else blank. (call this
ite-is-unique
)
You can now use this last column to filter your Inline List: “where ite-is-unique is true”
