Does VLOOKUP work with unsorted data?

All the three lookup functions Vlookup, Hlookup and Lookup work well with sorted data. But the Vlookup and Hlookup work both on sorted as well as unsorted data and that you can set by entering TRUE/FALSE as the last parameter.

Does VLOOKUP work without sorting?

VLOOKUP will scan values in column G for the lookup value. If an exact match is found, VLOOKUP will use it. If not, VLOOKUP will “step back” and match the previous row. This means table_array must be sorted in ascending order by lookup value to use approximate match.

Does column order matter in VLOOKUP?

VLOOKUP only looks right When lookup values appear in the first (leftmost) column, this limitation doesn’t mean much, since all other columns are already to the right. However, if the lookup column appears inside the table somewhere, you’ll only be able to lookup values from columns to the right of that column.

Does VLOOKUP work with hidden columns?

If you are familiar with the VLOOKUP command in Excel you may be interested to know that Vlookup counts hidden columns as well as the visible columns when deciding which columns information to bring back.

Can search in an unsorted list?

What is the best search method for an unsorted list of data?

Sequential search is the best that we can do when trying to find a value in an unsorted array. 1 But if the array is sorted in increasing order by value, then we can do much better. We use a process called binary search.

Why you should never use VLOOKUP?

It can not lookup and return a value which is to the left of the lookup value. It works only with data which is arranged vertically. VLOOKUP would give a wrong result if you add/delete a new column in your data (as the column number value now refers to the wrong column).

What are V lookups?

VLOOKUP stands for ‘Vertical Lookup’. It is a function that makes Excel search for a certain value in a column (the so called ‘table array’), in order to return a value from a different column in the same row.

Why is VLOOKUP returning wrong value?

If you get a wrong value from VLOOKUP, it is probably because you input TRUE here. You don’t input anything as your search mode when you want an exact match. If you don’t input anything, then VLOOKUP assumes you want TRUE (approximate match) there. You haven’t sorted the first column of your cell range inpu.
