Many a times, we come across to deal with Strings. Like Length of the String, Concatenating two or more Strings etc. This article teaches you how to deal with strings with the following different operations:

1. Concatenating Strings (Joining Strings)
2. Finding Length of a String (Len Function)
3. Remove Spaces from a String (Trim Function)
4. Left Function
5. Right Function
6. MID Function
7. InStr Function
8. Chr Function
9. Asc Function

Concatenating Strings (Join Strings) :

In Excel VBA, two strings can be Joined simply by adding them by using & sign. Refer the below example.

Private Sub CommandButton1_Click()
Dim Strng1, Strng2, Strng3, RsltStrng As String
Strng1 = "My Name "
Strng2 = "Is "
Strng3 = "Vish"
RsltStrng = Strng1 & Strng2 & Strng3
MsgBox (RsltStrng)
End Sub
Result:

My Name Is Vish

Len Function

This Function is basically used to get the length of the String (Count of All letters including Spaces of a String).
It returns an Integer Value.

Syntax:
=Len(String)

Example

=Len (Vishwa) = 6 and =Len (Learn Excel Macro) = 17

Right Function

The Right function extracts the right part of a String.
Syntax:
Right (, n)

Where:
Str : Is the Original String.
n : Number of Character to be extracted from Right of the Original String
 
Example:

Right(“Learn Excel Macro”, 5) = Macro

Left Function

The Left function extract the left part of a String.

Syntax:
Left (Str, n)

Where:
Str : Is the Original String.
n : Number of Character to be extracted from Left of the Original String
 
Example:

Left(“Learn Excel Macro”, 5) = Learn

Ltrim Function

The Ltrim function trims the empty spaces of the left portion of the String.

Syntax:
=Ltrim(String)

Example:

Ltrim (” Learn Excel Macro “)= Learn Excel Macro

Rtrim Function

The Rtrim function trims the empty spaces of the right part of the String.
Syntax:
=Rtrim(String)

Example:

Rtrim (” Learn Excel Macro “) = Learn Excel Macro

Trim function

Trim Function is combination of both RTrim and LTrim. It means, it removes all the spaces from Left and Right both the sides.
Syntax:

=Trim(String)

Example:

Trim (“ Learn Excel Macro ”) = Learn Excel Macro

Mid Function

The Mid function extracts a sub-string from the original phrase or string. It takes the following format:
Syntax:
Mid(string, position, n)
Where:

String : The Original String
Position : Starting position from where extraction should start
n : Number of Characters from the Start position

Example:

Mid(“Learn Excel Macro”, 3, 5) = rn Ex

InStr function

The InStr function looks for a phrase or string that is embedded within the original phrase and returns the starting position of the embedded phrase. Basically this is a search function within a string.
Syntax:

Instr (n, String, Search)

Where:
n : Place from where Search Phrase will be started searching
String : Original String where search string will be searched
Search : It is a search String which is searched in the Original String
 
Example:
Instr(1, “Learn Excel Macro, “Excel”)=7

Note:It returns the position number where that Search String is found. In the above example, Excel word is found from 7th position of the Original String. That is why it returns 7.

Ucase and the Lcase functions

The Ucase function converts all the characters of a string to capital letters. On the other hand, the Lcase function converts all the characters of a string to small letters.

Example:

Ucase(“Learn Excel Macro”) =LEARN EXCEL MACRO

Lcase(“Learn Excel Macro”) =learn excel macro

Str and Val functions

The Str is the function that converts a number to a string while the Val function converts a string to a number. The two functions are important when we need to perform mathematical operations.

Chr and the Asc functions

The Chr function returns the string that corresponds to an ASCII code while the Asc function converts an ASCII character or symbol to the corresponding ASCII code. There are 255 ASCII codes and as many ASCII characters.

The format of the Chr function is

Chr(charcode)

and the format of the Asc function is

Asc(Character)

Example:

Chr(65)=A
Chr(122)=z
Asc(“B”)=66
