The built-in function VLOOKUP is one of the most powerful functions in LO Calc. But it has some disadvantages - it compares values in only one column and only in the leftmost column. But if you need to compare values in 2 columns and not only in the first column?
The modified function VLOOKUPDOUBLE searches for two conditions in two different columns of the table at the same time.
=VLOOKUPDOUBLE(LookupValue1; LookupArray1; LookupValue2; LookupArray2; ReturnArray)
The VLOOKUPDOUBLE() function is easy to use. You just need to specify 2 separate ranges to search, 2 values to compare and a column from which the related values will be returned and LibreOffice Calc will automatically find and return the required result on two matches:
=VLOOKUPDOUBLE("John"; {Lookup Array1}; "001"; {Lookup Array2}; {Return Array})
We will have the following result:
This example uses the following values:
You can use the function VLOOKUPDOUBLE() by setting the extension " YouLibreCalc.oxt ". After that, this function will be available in all files that will be opened in LibreOffice Calc.
