Creating Defined Name with Formula in Excel
Defined names or Custom Formula are used to simply the long formula into a short & meaningful name.
These names can be defined in Excel from Menu -> Formula -> Name Manager -> New
There are four parameters to define a Name
- Name for definition
- Scope (workbook or specific worksheet)
- RefersTo – Actual formula with reference or another defined name
You can also create a defined name using VBA code also as given below:
VBA Code to Create Defined name or Custom FormulaVBA Create Defined name in ExcelVisual Basic123456789101112131415161718Sub Add_Defined_Name()Dim dName As Name, iRow As Double'Add a Defined Name'Scope: For Specific SheetActiveWorkbook.Worksheets("Sheet1").Names.Add Name:="chking", RefersTo _:="=Sheet1!$A$2"'Add a Defined Name'Scope: For whole WorkbookThisWorkbook.Names.Add Name:="sumDE", RefersTo:= _"=Sheet1!$D$1+Sheet1!$E$1"'Use a Defined nameThisWorkbook.Sheets(1).Range("D1") = 4ThisWorkbook.Sheets(1).Range("E1") = 2ThisWorkbook.Sheets(1).Range("F1") = "=sumDE"End Sub
In this Code, we are creating 2 defined names. One is SUMDE. This will sum the values in cells D1 & E1.
After executing this macro, you can enter =SumDE in any cell & press Enter key. Excel will sum the values in D & E, giving the result.

Manage Multiple Complex Formula using Defined Names
Similar to this, you can define any complex formula & associate it to a defined name. Then use only that defined name in any cell. This will simplify the maintenance of Formula.
In future if there are any changes to the formula, you doon;y have to search whole workbook on where this formula is used. You can just go to Menu -> Formula -> Names Manager. Choose the specific name, edit the formula in it & same it.
The whole workbook will be refreshed for the changed formula. Not many people are using this feature. But this is a very sophisticated way to manage any number of formula in a Workbook.
