This post will guide you how to extract number from a given test string in Excel. How do I extract all numbers from string using a formula in Excel. How to get all number from a given test string using user defined function in Excel.
Assuming that you have a list of data in range B1:B5, in which contain text string values, and you want to eextract all numbers from each cell in which contain letters and numbers. In other words, you wish to remove all letters from those text strings. And this post will show you two methods to accomplish it.
Extract Number from String with Formula
If you want to extract numbers from a range of cells that contain text string values, you need to use an array formula based on the SUM function, MID function, LARGE function, INDEX function, ISNUBER function and the ROW function to extract all numbers from one cell that contain text string values. Like this:
=SUM(MID(0&B1,LARGE(INDEX(ISNUMBER(MID(B1,ROW($1:$99),1))*ROW($1:$99),),ROW($1:$99))+1,1)*10^ROW($1:$99)/10)
You need to type this formula into a blank cell and press Ctrl + Shift +Enter key on your keyboard to change the current common formula as Array formula. Then drag the AutoFill handle down to other cells.
Note: B1 is the cell that you want to extract numbers from.
Extract Number from String with User Defined Function
You can also use an VBA code to define a User defined function to accomplish the same result of extracting all numbers from text string in Excel. Just do the following steps:
Step1# open your excel workbook and then click on “Visual Basic” command under DEVELOPER Tab, or just press “ALT+F11” shortcut.
Step2# then the “Visual Basic Editor” window will appear.
Step3# click “Insert” >”Module” to create a new module.
Step4# paste the below VBA code into the code window. Then clicking “Save” button.
[vb]
Function extractNumbers(Txt As String) As String
With CreateObject("VBScript.RegExp")
.Global = True
.Pattern = "\D"
extractNumbers = .Replace(Txt, "")
End With
End Function
[/vb]
#5 back to the current worksheet, then type the following formula in a blank cell, and then press Enter key. And drag the AutoFill Handle over to other cells.
