Excel 2010, Microsoft Office. Syntax. The syntax for the VLOOKUP function in Microsoft Excel is: VLOOKUP( value, table, index_number, [approximate_match]) Parameters or Arguments. Tips for Optimizing Performance Obstructions. Lookups are frequently significant calculation obstructions. Fortunately, there are many ways of improving lookup calculation time. If you use the exact match option, the calculation time for the function is proportional to the number of cells scanned before a match is found. For lookups over large ranges, this time can be significant. Lookup time using the approximate match options of VLOOKUP, HLOOKUP, and MATCH on sorted data is fast and is not significantly increased by the length of the range you are looking up. Characteristics are the same as binary search. Lookup Options. Ensure that you understand the matchtype and range- lookup options in MATCH, VLOOKUP, and HLOOKUP. The following code example shows the syntax for the MATCH function. For more information, see the Match method of the Worksheet. Function object. MATCH(lookup value, lookup array, matchtype). Matchtype=1 returns the largest match less than or equal to the lookup value if the lookup array is sorted ascending (approximate match). This is the default option. Matchtype=0 requests an exact match and assumes that the data is not sorted. Matchtype=- 1 returns the smallest match greater than or equal to the lookup value if the lookup array is sorted descending (approximate match). The following code example shows the syntax for the VLOOKUP and HLOOKUP functions. For more information, see the VLOOKUP and HLOOKUP methods of the Worksheet. Function object. VLOOKUP(lookup value, table array, col index num, range- lookup). HLOOKUP(lookup value, table array, row index num, range- lookup). Range- lookup=TRUE returns the largest match less than or equal to the lookup value (approximate match). This is the default option. Table array must be sorted ascending. Range- lookup=FALSE requests an exact match and assumes the data is not sorted. Avoid performing lookups on unsorted data where possible because it is slow. If your data is sorted, but you want an exact match, see Sorted Data with Missing Values. VLOOKUP vs. INDEX and MATCH or OFFSETTry using the INDEX and MATCH functions instead of VLOOKUP. VLOOKUP is slightly faster (approximately 5 percent faster), simpler, and uses less memory than a combination of MATCH and INDEX, or OFFSET. However, the additional flexibility that MATCH and INDEX offer often enables you to significantly save time. For example, you can store the result of an exact MATCH in a cell and reuse it in several INDEX statements. The INDEX function is fast and is a non- volatile function, which speeds up recalculation. The OFFSET function is also fast. However, it is a volatile function, and it sometimes significantly increases the time taken to process the calculation chain. It is easy to convert VLOOKUP to INDEX and MATCH. The following two statements return the same answer. VLOOKUP(A1, Data!$A$2: $F$1. False). INDEX(Data!$A$2: $F$1. MATCH(A1,$A$1: $A$1. Speeding Up Lookups. Because exact match lookups can be slow, consider the following options for improving performance: Use one worksheet. It is faster to keep lookups and data on the same sheet. When you can, SORT the data first (SORT is fast), and use approximate match. When you must use an exact match lookup, restrict the range of cells to be scanned to a minimum. Use dynamic range names rather than referring to a large number of rows or columns. Sometimes you can pre- calculate a lower- range limit and upper- range limit for the lookup. Sorted Data with Missing Values. Two approximate matches are significantly faster than one exact match for a lookup over more than a few rows. The breakeven point is about 1. If you can sort your data but still cannot use approximate match because you cannot be sure that the value you are looking up exists in the lookup range, you can use this formula. IF(VLOOKUP(lookup_val ,lookup_array,1,True)=lookup_val, _. VLOOKUP(lookup_val, lookup_array, column, True), "notexist"). The first part of the formula works by doing an approximate lookup on the lookup column itself. VLOOKUP(lookup_val ,lookup_array,1,True). If the answer from the lookup column is the same as the lookup value, use the following formula. IF(VLOOKUP(lookup_val ,lookup_array,1,True)=lookup_val. You have found an exact match, so you can do the approximate lookup again, but this time, return the answer from the column you want. VLOOKUP(lookup_val, lookup_array, column, True). If the answer from the lookup column did not match the lookup value, it is a missing value, and it returns "notexist". Be aware that if you look up a value smaller than the smallest value in the list, you receive an error. You can handle this error by using IFERROR, or by adding a small test value to the list. Unsorted Data with Missing Values. If you have to use exact match lookup on unsorted data, and you cannot be sure whether the lookup value exists, you often have to handle the #N/A that is returned if no match is found. In Excel 2. 00. 7, you can use the IFERROR function, which is both simple and fast. IF IFERROR(VLOOKUP(lookupval, table, 2 FALSE),0). In earlier versions, a simple but slow way is to use an IF function that contains two lookups. IF(ISNA(VLOOKUP(lookupval,table,2,FALSE)),0,_. VLOOKUP(lookupval,table,2,FALSE)). You can avoid the double exact lookup if you use exact MATCH once, store the result in a cell, and then test the result before doing an INDEX. In A1 =MATCH(lookupvalue,lookuparray,0). In B1 =IF(ISNA(A1),0,INDEX(tablearray,A1,column)). If you cannot use two cells, use COUNTIF. It is generally faster than an exact match lookup. IF (COUNTIF(lookuparray,lookupvalue)=0, 0, _. VLOOKUP(lookupval, table, 2 FALSE)). Exact Match Lookups on Multiple Columns. You can often reuse a stored exact MATCH many times. For example, if you are doing exact lookups on multiple result columns, you can save time by using one MATCH and many INDEX statements rather than many VLOOKUP statements. Add an extra column for the MATCH to store the result (stored_row), and for each result column use the following. INDEX(Lookup_Range,stored_row,column_number). Alternatively, you can use VLOOKUP in an array formula. VLOOKUP(lookupvalue,{4,2},FALSE)}. Looking Up a Set of Contiguous Rows or Columns. You can also return many cells from one lookup operation. To look up several contiguous columns, you can use the INDEX function in an array formula to return multiple columns at once (use 0 as the column number). You can also use the INDEX function to return multiple rows at one time. INDEX($A$1: $J$1. This returns column A to column J from the stored row created by a previous MATCH statement. Looking Up a Rectangular Block of Cells. You can use the MATCH and OFFSET functions to return a rectangular block of cells. Two- Dimensional Lookup. You can efficiently do a two- dimensional table lookup using separate lookups on the rows and columns of a table by using an INDEX function with two embedded MATCH functions, one for the row and one for the column. Multiple- Index Lookup. In large worksheets, you may frequently need to look up using multiple indexes, such as looking up product volumes in a country. To do this, you can concatenate the indexes and perform the lookup by using concatenated lookup values. However, this is inefficient for two reasons: Concatenating strings is a calculation- intensive operation. The lookup will cover a large range. It is often more efficient to calculate a subset range for the lookup (for example, by finding the first and last row for the country, and then looking up the product within that range). Three- Dimensional Lookup. To look up the table to use in addition to the row and the column, you can use the following techniques, focusing on how to make Excel look up or choose the table. If each table you want to look up (the third dimension) is stored as a set of named structured tables, range names, or as a table of text strings that represent ranges, you might be able to use the INDIRECT or CHOOSE functions. Using CHOOSE and range names can be an efficient method.
