Pay attention when you concatenate

Pay attention when you concatenate

21 February 2015

In many case, we may want to combine texts from different cells. This can be done by either CONCATENATE function or simply an ampersand &.

If you are doing so because you want to perform VLOOKUP with 2 lookup values, the robust way to combine texts should include a delimiter in between, e.g. A1 & "|" & B1.

Why? Because laziness has a price.
