VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

lookup_value: The value you want to look up.
table_array: The range of cells that curb the information.
col_index_num: The column number in the table from which to regress a value.
range_lookup: (Optional) A consistent value that delineate whether you desire VLOOKUP to find an exact lucifer or an rough match.

lookup_value: The value you want to seem up.
table_array: The reach of cell that contains the data.
row_index_num: The row number in the table from which to return a value.
range_lookup: (Optional) A logical value that stipulate whether you require HLOOKUP to find an precise match or an approximate match.

The syntax for INDEX is:

INDEX(array, row_num, [column_num])

array: The range of cell.
row_num: The row number in the array from which to revert a value.
column_num: (Optional) The column number in the regalia from which to return a value.

The syntax for MATCH is:

MATCH(lookup_value, lookup_array, [match_type])

lookup_value: The value you want to discover.
lookup_array: The ambit of cells being searched.
match_type: (Optional) The case of match: 1 for approximative lucifer, 0 for accurate lucifer, -1 for orotund value less than or equal to lookup_value.

By combining INDEX and MATCH, you can execute lookups that are more flexible than those potential with VLOOKUP or HLOOKUP. for instance, you can look up a value in any column of a table and return a value from any row or column.

XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])

lookup_value: The value you want to seem up.
lookup_array: The range of cell being search.
return_array: The orbit of cell carry the value to return.
if_not_found: (Optional) The value to return if no match is found.
match_mode: (Optional) The type of lucifer: 0 for exact lucifer, -1 for precise match or the largest value less than lookup_value, 1 for exact lucifer or the small-scale value great than lookup_value, 2 for wildcard fibre lucifer.
search_mode: (Optional) The search fashion: 1 for search firstly to last, -1 for search last to foremost, 2 for binary search rise, -2 for binary search descending.

XLOOKUP offers several advantages over traditional lookup use, include the power to seek in any column, return multiple value, and handle errors more gracefully. for instance, you can use XLOOKUP to find the name of an employee base on their ID and regress their section and salary in separate cell.
