Updated the table_array argument each time the data changes to include the additional data (this method requires regular updates/changes to the VLOOKUP formula).Included a table_array which is significantly bigger than required so that future data can be added (this method can result in slower calculation times).If you have experienced this, you probably followed one of the following methods: But, there are also circumstances when additional rows will be added onto the existing data, therefore the exact data ranage is not known. When using the VLOOKUP function, we often know how many rows there are in the data, therefore we know which cell references to include in the table_array.

For example, in the code below A1:C9 is the table_array.


This is the range of cells which contains the data to be used within the VLOOKUP function. The 2nd argument in the VLOOKUP function is the table_array.
