## How to look up the next smaller item or the next larger item

The XLOOKUP function searches a range or an array for a match and returns the corresponding item from a second range or array. The syntax of the XLOOKUP function is as follows: = XLOOKUP ( lookup_value ; lookup_array ; return_array ; if_not_found ; match_mode ; search_mode ) The lookup value can be either a text or a number, inputted directly into the function or as a cell reference.   When looking up numbers, other than match type 0, exact match,

## How to use less than or greater than MATCH

We can use the INDEX function to designate a cell range (array) from which we want to retrieve data and, at the same time, use the MATCH function to specify the address of a cell in that cell range (array), i.e., row and column.   The MATCH function returns the relative position of the item in the range, either a row or a column. The relative position is returned in the form of an integer number, such as 1, 2,

## Combining FILTER with XLOOKUP

The FILTER function allows us to filter a range of data based on criteria defined for specified corresponding arrays. By combining FILTER with XLOOKUP, that corresponding array and/or filtering criteria can be returned from (un)related tables. We can FILTER, and in the end, SUM, values based on criteria that are not present in the table we are returning values from.   In the following example, we will show how to use XLOOKUP in order to return filtering criteria: This table

## Combining FILTER with INDEX MATCH

The FILTER function allows us to filter a range of data based on criteria defined for specified corresponding arrays. By combining FILTER with INDEX MATCH, that corresponding array and/or filtering criteria can be returned from (un)related tables. We can FILTER, and in the end, SUM, values based on criteria that are not present in the table we are returning values from.   In the following example, we will show how to use INDEX MATCH in order to return filtering criteria:

## SEQUENCE function

The SEQUENCE function generates a list of sequential numbers in an array. We can generate a list of sequential numbers in rows, columns, or both. By default, the SEQUENCE function will return multiple values, which will be placed in the neighboring cells (to the bottom and/or to the right). I.e., we are dealing with dynamic array formulas here.   The syntax of the SEQUENCE function is as follows: =SEQUENCE ( rows ; [columns] ; [start] ; [step] ) Rows specifies

## FILTER function

The FILTER function replicates and extends Excel AutoFilter filtering functionality in formula form. The FILTER function allows us to filter a range of data based on defined criteria. By default, the FILTER function will return multiple values, which will be placed in the neighboring cells (to the bottom and/or to the right). I.e., we are dealing with dynamic array formulas here.   The syntax of the FILTER function is as follows: = FILTER ( array ; include ; [if_empty] )

## Date and Time in Excel

How are date and time stored and formatted? No matter how date and/or time are formatted and possibly edited, the underlying values saved in cells are still decimal numbers. Given that Excel’s era starts on January 1, 1900, if we enter number 1 in the cell and format it as a date, the date we will see is in fact January 1, 1900.Zero will provide for a nonexistent date of January 0, 1900, and a negative number will result in
