This is useful. Thanks a lot. I don't understand why though, in the first 4 paragraphs, columns are indexed as such: column B's index is 1, column C's index is 2,..., column E's index is 4 and column F's index is 5"... ... But on the 5th paragraph "5. VLOOKUP Column Index Number Increase Using the COLUMN Function", it is said that column E's index is 5 and column F's index is 6: "*Now, as we are using the formula in Column E and F, the COLUMN function will return 5 and 6 respectively. In the sheet, column E’s index number is 5. And column F’s index number is 6.*"
