Lookup data from different sheet

New to LibreCalc. Well aware that the question must have been asked before, but I’m probably not phrasing it correctly as cannot find the solution.

I have 2 sheets containing customer info. Each sheet has column customerID.

Sheet1 has all customers who have created an account. There are 60000 of them
Sheet2 has just 2 columns - customerID and total spend

There are about 50000 entries in Sheet2

All I’m trying to do is look up the customerID in Sheet 2 to match the customerID in Sheet1 and copy the total spend to the appropriate row in Sheet 1.

I know this can’t be that difficult, but I just can’t get it working.

Thanks for helping out a newbie

VLOOKUP is one tool you could use. [Edited link to more recent Help page]

Ah- had overlooked the additon of FALSE.

Thanks. I’m aware of the VLOOKUP but can’t seem to get my head round it. This is a simplified demo of what I’m trying to do

I want to insert the value of D into B when value of A equals the value of C.

So Col B Rows 2,3,5,6 and 9 should remain empty.

Using =VLOOKUP(A1,$C:$D,2) and copying down simply fills all rows…

  • although it does at least show the change at the correct row as indicated. How do I omit the data in B2,3,5,6 and 9?

Many thanks.

Hi, using your example, try the following, =IFNA(INDEX($D$1:$D$5,MATCH(A1,$C$1:$C$5,0),0)," ")
