I am trying to create a simple VLOOKUP function for my spreadsheet using the below: In the first sheet
=VLOOKUP(\"Salary\",\'December 2015_natwest_download\'
The VLOOKUP function is designed to lookup a value on the far left of a block of data and return a corresponding value from a column to the right.
If you need to lookup a value and return a value from a corresponding column to the left of the lookup column, you need to use an INDEX/MATCH function pair.
If you are returning numbers based on a condition (either in that column or another column) either the SUMIF or SUMIFS function will do. Individual entries can be easily collected but if there is more than a single match to your condition, you will receive a sum total of the matching numbers.
The formulas in E4:F4 are,
=INDEX('December 2015_natwest_download'!A:A, MATCH(D4, 'December 2015_natwest_download'!B:B, 0))
=SUMIFS('December 2015_natwest_download'!A:A,'December 2015_natwest_download'!B:B, D4)
Note that the SUMIFS in F5 is returning two Gym entries.
