To find a value in a table, you need to first know the range. For example, if the range contains a value 10251, it will find it in the first column of the second column. In this case, we would use the SMALL(array, k) function to find an exact match. In this way, we would return the value of 10251 as the returned value.
The VLOOKUP function is a key feature of Excel. This function scans a table or dynamically updates data to retrieve data based on a lookup value. The VLOOKUP function has two modes: exact match and approximate match. However, you can use the latter when you want to compare two cells with different lookup values. You can also use conditional formatting to highlight cells that contain the same code.
The most common use of the VLOOKUP function is to compare two columns. The first lookup value is in the first column of the range. In other words, the column number must be C. This way, the formula will match both columns. The second lookup value should be B. You can use a formula similar to the previous one to check the range for matches. Alternatively, you can use the VLOOKUP function to compare two values in different columns.
The second use of the VLOOKUP function involves using a helper column. A helper column uses a formula to create unique qualifiers. This is an important part of the formula because it will help you find the right value. It is best used with existing data and should not be used for complex queries. But if you have existing data, VLOOKUP can still work. But you should consider restructured data or a pivot table instead.
