How to use the vlookup in Microsoft excel.
Solutie
VLOOKUP is an Excel function to lookup and retrieve data from a specific column in table.Supports approximate and exact matching, and wildcards (* ?) for partial matches. The “V” stands for “vertical”. Lookup values must appear in the first column of the table, with lookup columns to the right.
Purpose
Lookup a value in a table by matching on the first column
Return value
The matched value from a table.
Syntax
=VLOOKUP (value, table, col_index, [range_lookup])
Arguments
- value – The value to look for in the first column of a table.
- table – The table from which to retrieve a value.
- col_index – The column in the table from which to retrieve a value.
- range_lookup – [optional] TRUE = approximate match (default). FALSE = exact match.
VLOOKUP only looks right
VLOOKUP requires a lookup table with lookup values in the left-most column. The data you want to retrieve (result values) can appear in any column to the right.
VLOOKUP retrieves data based on column number
When you use VLOOKUP, imagine that every column in the table is numbered, starting from the left. To get a value from a particular column, simply supply the appropriate number as the “column index”.
VLOOKUP has two matching modes, exact and approximate
VLOOKUP has two modes of matching: exact and approximate, which are controlled by the 4th argument, called “range_lookup”. Set range_lookup to FALSE to force exact matching, and TRUE for approximate matching.
Important: range_lookup defaults to TRUE, so VLOOKUP will use approximate matching by default
- Range_lookup controls whether value needs to match exactly or not. The default is TRUE = allow non-exact match.
- Set range_lookup to FALSE to require an exact match and TRUE to allow a non-exact match.
- If range_lookup is TRUE (the default setting), a non-exact match will cause the VLOOKUP function to match the nearest value in the table that is still less than value.
- When range_lookup is omitted, the VLOOKUP function will allow a non-exact match, but it will use an exact match if one exists.
- If range_lookup is TRUE (the default setting) make sure that lookup values in the first row of the table are sorted in ascending order. Otherwise, VLOOKUP may return an incorrect or unexpected value.
- If range_lookup is FALSE (require exact match), values in the first column of table do not need to be sorted.
