We need to update 1000's of record (which are in a excel file) wherein which the first column has the Unique ID's. The problem is Unique ID is duplicated.

This is how my file will look like. "Sample - ID" (Column C) is unique and it's duplicated. But one set of sample id will have values in one cell and the other duplicate sample id will have value in another cell. (Eg: NRC 101 - 014, first row M3 - N3 value is blank. But the second row M3 -N3 has values). We have to retain both.
I've tried with vlookup but it's not working. What i want is if the one cell value is blank, check for the Sample-ID w.r.t header and fill the value from the next non-blank cell for the same sample id.

Whats the difference between CONCAT and CONCATENATE?
The newer CONCAT function can reference a range of cells. =CONCATENATE(A1,A2,A3,A4,A5) becomes =CONCAT(A1:A5)
