I would like to be sure that all my cell contain only characters (A-Z/a-z). I want to be sure there isn't any symbol, number or anything else. Any tips?
For example I have this "Š".
As a VBA function, the following should work:
Option Compare Binary
Function LettersOnly(S As String) As Boolean
LettersOnly = Not S Like "*[!A-Za-z]*" And S <> ""
End Function
In using the function, S can be either an actual string, or a reference to the cell of concern.
EDIT: Also, you want to be certain you have not set Option Compare Text in your code. The default is Option Compare Binary which is what you want for this type of comparison. I have added that to the code for completeness.
Open the VBA editor (Alt+F11) and create a new module.
Add a reference to "Microsoft VBScript Regular Expressions 5.5" (Tools -> References).
In your new module, create a new function like this:
Function IsAToZOnly(inputStr As String) As Boolean
Dim pattern As String: pattern = "^[A-Za-z]*$"
Dim regEx As New RegExp
regEx.pattern = pattern
IsAToZOnly = regEx.Test(inputStr)
End Function
Use the new function in your worksheet:
=IsAToZOnly(A1)

I wish to use the find and replace function in excel to remove example sentences from cells similar to this:
text <br>〔「text」text，「text」text〕<br>（１）text「sentence―sentence/sentence」<br>（２）text「sentence―sentence」
Sentences are in between 「」brackets and will include a ― and / character somewhere inside the brackets.
I have tried 「*―*/*」 however this will delete everything from the right of the〔
Is there any way to target and delete these specific sentence brackets, with the find and replace tool?
Desired outcome:
text <br>〔「text」text，「text」text〕<br>（１）text<br>（２）text「sentence―sentence」
Quite a long formula but in Excel O365 you could use:
=SUBSTITUTE(CONCAT(FILTERXML("<t><s>"&SUBSTITUTE(CONCAT(IF(MID(A1,SEQUENCE(LEN(A1)),1)="「","</s><s>「",IF(MID(A1,SEQUENCE(LEN(A1)),1)="」","」</s><s>",MID(A1,SEQUENCE(LEN(A1)),1)))),"<br>","|$|")&"</s></t>","//s[not(contains(., '「') and contains(., '―') and contains(., '/') and contains(., '」'))][node()]")),"|$|","<br>")
As long as you have access to CONCAT you could also do this in Excel 2019 but you'll have to swap SEQUENCE(LEN(A1)) for ROW(A$1:INDEX(A:A,LEN(A1)))
This formula won't work in many cases, but if the string has matching rules as in your example, then try this:
=SUBSTITUTE(C5,"「" & INDEX(TRIM(MID(SUBSTITUTE(","&SUBSTITUTE(C5,"」","「"),"「",REPT(" ",99)),(ROW(A1:INDEX(A1:A100,LEN(C5)-LEN(SUBSTITUTE(C5,"」",""))))*2-1)*99,99)),MATCH("*―*/*",TRIM(MID(SUBSTITUTE(","&SUBSTITUTE(C5,"」","「"),"「",REPT(" ",99)),(ROW(A1:INDEX(A1:A100,LEN(C5)-LEN(SUBSTITUTE(C5,"」",""))))*2-1)*99,99)),0)) & "」","")
explain how it works:
split the string between the characters "「 "and "」" into an array
use match("*―*/*",,0) to find the string position (note that it will only return one value if it exists, if you have multiple strings, you can replace match("*―*/*",) with search ("*―*/*",..) and use it as an extra column to get matches string)
Use the index(array,match("*―*/*",..)) to get the string needs replacing (result)
Replace the original string with the results found =substitute(txt,result,"")
Or,
In B1 enter formula :
=SUBSTITUTE(A1,"「"&TRIM(RIGHT(SUBSTITUTE(LEFT(A1,FIND("」",A1,FIND("/",A1))),"「",REPT(" ",99)),99)),"")
You did not tag [VBA], but if you are not averse, you could write a User Defined Function that would do what you want using Regular Expressions.
To enter this User Defined Function (UDF), alt-F11 opens the Visual Basic Editor.
Ensure your project is highlighted in the Project Explorer window.
Then, from the top menu, select Insert/Module and
paste the code below into the window that opens.
To use this User Defined Function (UDF), enter a formula like =replStr(A1) in some cell.
Option Explicit
Function replStr(str As String) As String
Dim RE As Object
Const sPat As String = "\u300C(?:(?=[^\u300D]*\u002F)(?=[^\u300D]*\u2015)[^\u300D]*)\u300D"
Set RE = CreateObject("vbscript.regexp")
With RE
.Global = True
.Pattern = sPat
replStr = .Replace(str, "")
End With
End Function
I have essentially a simple syntax question concering Application.Run. I want to write a bit of code where I pass a UDF a string coantaining the name of a worksheet function, e.g. 'iserror' or some other UDF returning boolean. The function will then be exectued for each cell within the passed range and do something depending on result.
However, I have not been able to work out the proper Syntax. Error Messages Change along with my Trials, but non are particularly helpfull. e.g.:
?hrCull(Range("Data!A1:B10"),"Worksheetfunction.iserror", False)
(Error message in German, I'll try my best to translate, but it probably won't 100% match the English Version):
Runtime error 1004:
The macro 'Worksheetfunction.iserror' can not be exectued. The macro may not be available in this worksheet or macros have been deactivated.
Of course, macros have not been deactivated, but it isn't really a macro anyway. Also tried without the leading 'Worksheetfunction', same error message.
In my code the call Looks like this:
Public Function hrCull(r As Range, func As String, Optional invert As Boolean = False) As Range
Dim c As Range
Dim selector As Boolean
...
selector = Application.Run(func, c)
...
end function
I omitted code not relevant.
So what is the proper Syntax?
Misc:
- I'm Aware that I can not assert that the passed function returns a boolean.
- Excel 2016 on Windows 7
A solution using CallByName:
selector = CallByName(Application.WorksheetFunction, "IsError", VbMethod, c)
Lose the WorksheetFunction. prefix, Evaluate doesn't like it as Evaluate is for worksheet functions.
In your function, use:
selector = Application.Evaluate(func & "(" & c.Address & ")")
To test, use:
Debug.Print hrCull(Range("A1"), "ISERROR")
I think you'd be better off declaring your own Enum and adding the functions that you want into this. Then execute them using built in syntax instead of trying to evaluate a string
Public Enum xlSheetFunction
xlIsError
End Enum
Public Function hrCull(r As Range, func As xlSheetFunction, Optional Invert As Boolean = False) As Range
Dim selector As Boolean
Select Case func
Case xlIsError
selector = WorksheetFunction.IsError(r)
End Select
Debug.Print selector
Set hrCull = r
End Function
Public Sub test()
Debug.Print hrCull(Range("A1"), xlIsError)
End Sub
The problem that I'm facing is that I have an entire column that has text separated by _ that contains pixel size that I want to be able to extract but currently can't. For example:
A
Example_Number_320x50_fifty_five
Example_Number_One_300x250_hundred
Example_Number_two_fifty_728x49
I have tried using Substitute function to grab the numbers which works but only grabs the numbers when I need something like: 320x50 instead I'm getting 0, as I'm not sure how to exactly extract something like this. If it was consistent I could easily do LEFT or RIGHT formula's to grab it but as you can see the data varies.
The result that I'm looking for is something along the lines of:
A | B
Example_Number_320x50_fifty_five | 320x50
Example_Number_One_300x250_hundred | 300x200
Example_Number_two_fifty_728x49 | 728x49
Any help would be much appreciated! If any further clarification is needed please let me know and I'll try to explain as best as I can!

I would probably use a Regular Expressions UDF to accomplish this.
First, open up the VBE by pressing Alt + F11.
Right-Click on VBAProject > Insert > Module
Then you can paste the following code in your module:
Option Explicit
Public Function getPixelDim(RawTextValue As String) As String
With CreateObject("VBScript.RegExp")
.Pattern = "\d+x\d+"
If .Test(RawTextValue) Then
getPixelDim = .Execute(RawTextValue)(0)
End If
End With
End Function
Back to your worksheet, you would use the following formula:
=getPixelDim(A1)
Looking at the pattern \d+x\d+, an escaped d (\d) refers to any digit, a + means one or more of \d, and the x is just a literal letter x. This is the pattern you want to capture as your function's return value.
Gosh, K Davis was just so fast! Here's an alternate method with similar concept.
Create a module and create a user defined function like so.
Public Function GetPixels(mycell As Range) As String
Dim Splitter As Variant
Dim ReturnValue As String
Splitter = Split(mycell.Text, "_")
For i = 0 To UBound(Splitter)
If IsNumeric(Mid(Splitter(i), 1, 1)) Then
ReturnValue = Splitter(i)
Exit For
End If
Next
GetPixels = ReturnValue
End Function
In your excel sheet, type in B1 the formula =GetPixels(A1) and you will get 320x50.
How do you create a user defined function?
Developer tab
Use this URL to add Developer tab if you don't have it: https://www.addintools.com/documents/excel/how-to-add-developer-tab.html
Click on the highlighted areas to get to Visual Basic for Applications (VBA) window.
Create module
Click Insert > Module and then type in the code.
Use the user defined function
Note how the user defined function is called.
I have an existing macro that I use to format columns. I've been using this without problems. Now, I'm looking to learn how to use Option Explicit and I am running into a problem with defining my variable.
What should I be dim'ing Level as? I tried Dim Level As String but that didn't work. I'm trying to get a better understanding so any feedback would be appreciated.
Option Explicit
Sub adviseformat()
Dim Form As Worksheet
Set Form = Sheets("Formatting")
With Form
Level = WorksheetFunction.Match("Level", .Rows("1:1"), 0)
.Columns(Level).Delete
.Columns("D:E").Delete
.Range("U:U").Value = Range("E:E").Value
.Columns("E").EntireColumn.Delete
.Columns("F:I").Delete
.Columns("I").Delete
.Columns("L").Delete
.Columns("M").Delete
Form.Range("A:B").EntireColumn.Insert
Form.Range("A1").Value = "Owner"
Form.Range("B1").Value = "Comment"
Form.Range("A1").Interior.Color = 65535
Form.Range("B1").Interior.Color = 65535
Form.Range("O1").Interior.Color = 65535
End With
End Sub
As you type the WorksheetFunction.Match part, the VBA editor should pop up and give you a clue to the return type. It should say something like:
Match(Arg1, Arg2, [Arg3]) as Double
The "As Double" part tells you the return type of the Match function. This is the type you should use to declare your Level variable.
Looking on MSDN, I found this :
MATCH returns the position of the matched value within lookup_array, not the value itself.
For example, MATCH("b",{"a","b","c"},0) returns 2, the relative position of "b" within the array {"a","b","c"}.
So my guess is that you should use Dim Level As Variant
I am trying to parse a string from teamspeak. I am new to the functions of excel. I have accomplished this with php but I am driving myself nuts excel. This is the string I am trying to parse:
[URL=client://4792/noEto+VRGdhvT9/iV375Ck1ZIfo=~Rizz]Rizz[/URL]
This is what I have accomplished so far:
=TRIM(MID(B22, 15, FIND("=",B22,12) - FIND("//",B22)))
which returns
4792/noEto+VRGdhvT9/iV375Ck1ZIfo=~
I am trying to get it to return:
noEto+VRGdhvT9/iV375Ck1ZIfo=
Any suggestions? I am looked of splitting of strings and the phrasing is just really confusing. Any help would be appriciated.
Paste the URL in A3, then this formula in B3. You can adjust the cell references as needed. It's a lot of nested functions, but it works.
=left(right(A3, len(A3)-find("/",A3,find("//",A3,1)+2)),find("=",right(A3, len(A3)-find("/",A3,find("//",A3,1)+2)),1))
Or you can use a user-defined function in VBA:
Function RegexExtract(myRange As Range) As String
'VBA Editor, menu Tools - References, add reference to Microsoft VBScript Regular Expressions 5.5
Dim regex As New RegExp, allMatches As MatchCollection
With regex
.Global = True
.pattern = "\d+/(.+=)"
End With
Set allMatches = regex.Execute(myRange.Value)
With allMatches
If .Count = 1 Then
RegexExtract = .Item(0).SubMatches(0)
Else
RegexExtract = "N/A"
End If
End With
End Function
Then use it as formula:
=RegexExtract(A1)
I am trying to parse a string
For that:
=MID(A1,20,28)
works.
Now if you have more than one string maybe the others are not of an identical pattern, so the above might not work for them. But in that case if to help you we'd need to know something about the shape of the others wouldn't we.
