To change or edit an array formula, you need to follow some rules, especially if you have multi-cell formulas. This article spells out the rules.

Excel formulas that return a set of values, also known as an array, return these values to neighboring cells. This behavior is called spilling . Formulas that can return arrays of variable size are called dynamic array formulas.

To fix that problem, you add the INDIRECT function to the formula: =ROW(INDIRECT("1:10")) The INDIRECT function uses text strings as its arguments (which is why the range 1:10 is surrounded by quotation marks). Excel does not adjust text values when you insert rows or otherwise move the array formula.

Excel can't calculate an array within an array. The nested array error occurs when you try to input an array formula that contains an array. To resolve the error, try removing the second array.

You can use constants in your array formulas or by themselves. In your array formula, type an opening brace, the values you want, and a closing brace. Here's an example: =SUM(A1:E1*{1,2,3,4,5})

See examples of how to enter the cell ranges (the table_array argument) in VLOOKUP and HLOOKUP functions.

Excel provides two types of array formulas: Array formulas that perform several calculations to generate a single result and array formulas that calculate multiple results. Some worksheet functions return arrays of values, or require an array of values as an argument.

Dynamic array formulas can automatically populate or "spill" into neighboring blank cells, and eliminate the need for legacy Ctrl+Shift+Enter (CSE) array formulas. When opening a workbook that contains dynamic array formulas in an older version of …

Problem: The array arguments don't have the same dimension. All of the array arguments should be the same dimension. If they're not, then you get the #VALUE! error. For example, if Array 1 refers to a range of 3 rows and 2 columns, then Array 2 must also correspond to the similar range. =SUMPRODUCT(D2:D13,E2:E10)

Problem: The formula has not been entered as an array. If you are using INDEX as an array formula along with MATCH in order to be able to retrieve a value, you will need to convert your formula into an array formula, otherwise you will see a #VALUE! error.
