I am trying to do vlookup on 50k, however every time Libreoffice calc gets in no-responding mode. Is there any other way to do vlookup in LibreOffice Calc?

Sorry, but let me tell that I not believe you! I have just tested the array of one million rows and VLOOKUP () worked very well. Maybe you have an error in a formula or in the data. Can you show your formula?

What is you have in cell A29? The text? Number? Date? What is you have in column A of the worksheet My_Data? Value types are the same? The entire length of the column? Try to change the formula to =vlookup(A29,$My_Data.$A$1:$B$157286,2,0)

Please opne a bug report with a test document. We are always interested in test documents showing performance problems because we think that we have fixed the most obvious ones and now need some help of users to find more during import or during execution of calculations.

Any help on this?

I am afraid that there is no help. You can try to fill in the search column in small portions - 1-2K. Then convert the result of the formula in the value and repeat. My experiments with alternative formulas searches lead to the same results - the computer for a long time to think.

I think you should use Base instead of Calc for such a amount of data. Base is much more powerful handling a big amount of data. Here's a OOo forum thread how to import a Calc sheet in Base.
