VBA Trim Function

When VBA has an answer to the Len function it stores it into the variable called LengthFullName. Feel free to install a fully functional 7-day trial version of Text Toolkit and see if it works for you using this. Sorry I can't assist you better.

The position you specify using Start is where it starts returning the string from. In the Unicode character set, there is one more space character called the non-breaking space, which is commonly used on web pages as the html character. Value Edit: If it appears to be stuck in a loop, I'd add Debug. All information about string manipulation in VBA together.

VBA Trim Function - Many cells have a space immediately preceding the line break and I want to include those particular spaces but no others. If you want to try this handy Excel Trim Spaces tool in your sheets, a 15-day evaluation version can be downloaded.

This post provides an in-depth guide to using string in VBA. It explains strings in simple terms with clear code examples. I have laid it out so the post can be easily used as a quick reference guide. If you are going to use strings a lot then I recommend you read the first section as it applies to a lot of the functions. Otherwise you can read in order or just go to the section you require. The following two points are very important when dealing with VBA string functions. The Original String is not Changed An important point to remember is that the VBA string functions do not change the original string. They return a new string with the changes the function made. If you want to change the original string you simply assign the result to the original string. See the section for examples of this. How To Use Compare Some of the string functions such as StrComp and Instr etc. This works as follows: vbTextCompare: Upper and lower case are considered the same vbBinaryCompare: Upper and lower case are considered different The following code uses the string comparison function StrComp to demonstrate the Compare parameter Sub Comp1 ' Prints 0 : Strings match Debug. Option Compare is set at the top of a Module. Any function that uses the Compare parameter will take this setting as the default. The two ways to use Option Compare are: 1. Option Compare Text: makes vbTextCompare the default Compare argument Option Compare Text Sub Comp2 ' Strings match - uses vbCompareText as Compare argument Debug. Option Compare Binary: Makes vbBinaryCompare the default Compare argument Option Compare Binary Sub Comp2 ' Strings do not match - uses vbCompareBinary as Compare argument Debug. Now that you understand these two important points about string we can go ahead and look at the string functions individually. Appending Strings ABC Cube Pile © Aleksandr Atkishkin Dreamstime. The following code shows some examples of using it Sub Append Debug. You may see the + operator being used to append strings. The difference is that this operator will only work with string types. If you try to use it with other type you will get an error. Extracting Part of a String The functions discussed in this section are useful when dealing with basic extracting from a string. For anything more complicated you might want to check out my post on. They are very simple functions to use. Left reads characters from the left, Right from the right and Mid from a starting point that you specify. Print Left sCustomer, 4 ' Prints: John Debug. Print Right sCustomer, 5 ' Prints: Smith Debug. Print Left sCustomer, 11 ' Prints: John Thomas Debug. Print Right sCustomer, 12 ' Prints: Thomas Smith Debug. Print Mid sCustomer, 1, 4 ' Prints: John Debug. Print Mid sCustomer, 6, 6 ' Prints: Thomas Debug. Print Mid sCustomer, 13, 5 ' Prints: Smith End Sub As mentioned in the previous section, VBA string functions do not change the original string. Instead, they return the result as a new string. If the search string is found then the position from the start of the check string of the search string is returned. If the search string is not found then zero is returned. If either string is null then null is returned. Therefore if there is only one instance of the search item then both InStr and InStrRev will return the same value. However, if you are going to use them for extracting text from a string they can make things complicated. I have written about a much better way to do this in my post. It simply returns the number of characters the string contains. If used with a numeric type such as long it will return the number of bytes. It simply returns the given string with the characters reversed. The following subsections describe how it is used. The following shows some examples of using equals to compare strings Option Compare Text Sub CompareUsingEquals ' Returns true Debug. It is essentially the opposite of using the equals sign as the following code shows Option Compare Text Sub CompareWithNotEqual ' Returns false Debug. For example, you may want to check that a customer number has 3 digits followed by 3 alphabetic characters or a string has the letters XX followed by any number of characters. If the string matches the pattern then the return value is true, otherwise it is false. Pattern matching is similar to the VBA Format function in that there are almost infinite ways to use it. In this section I am going to give some examples that will explain how it works. This should cover the most common uses. If you need more information about pattern matching you can refer to the for the Like operator. Lets have a look at a basic example using the tokens. Important Note on VBA Pattern Matching The Like operator uses either Binary or Text comparison based on the Option Compare setting. Please see the section on above for more details. It replaces all instances of the substring that are found by default. The default -1 means all. Count determines the number of substitutions to make. So for example, setting Count equal to one means that only the first occurrence will be replaced. Sub ReplaceCount ' Replaces first question mark only Debug. E The Start optional parameter allow you to return part of a string. The position you specify using Start is where it starts returning the string from. It will not return any part of the string before this position whether a replace was made or not. Sub ReplacePartial ' Use original string from position 4 Debug. You can use the Compare parameter to do this. This is used in a lot of string functions. For more information on this check out the section above. Sub ReplaceCase ' Replace capital A's only Debug. In the following code we want to replace X and Y with A and B respectively. Print newString End Sub In the next example we will change the above code to perform the same task. We will use the return value of the first replace as the argument for the second replace. Print newString End Sub The result of both of these Subs is XYCD XYDN Convert Types to String Basic This section is about converting numbers to a string. A very important point here is that most the time VBA will automatically convert to a string for you. Print s End Sub When you run the above code you can see that the number were automatically converted to strings. So when you assign a value to a string VBA will look after the conversion for you most of the time. There are conversion functions in VBA and in the following sub sections we will look at the reasons for using them. In this case you can use the Str or CStr functions. Both take an expression as a function and this can be any type such as long, double, data or boolean. Imagine you are reading a list of values from different types of cells to a collection. Add Str c Next ' Print out the collection values and type Dim i As Variant For Each i In coll Debug. Print i, TypeName i Next End Sub In the above example we use Str to convert the value of the cell to a string. The alternative to this would be to assign the value to a string and then assigning the string to the collection. So you can see that using Str here is much more efficient. Multi Region The difference between the Str and CStr functions is that CStr converts based on the region. If your macros will be used in multiple regions then you will need to use CStr for you string conversions. It is good practise to use CStr when reading values from cells. If your code ends up being used in another region then you will not have to make any changes to make it work correctly. Convert String to Number- CLng, CDbl, Val etc. If you are assigning to a variable of this type then VBA will do the conversion automatically. It means you can determine the type at runtime. In the following code we set the type based on the sType argument passed to the PrintValue function. As this type can be read from an external source such as a cell, we can set the type at runtime. If we declare a variable as Long then it will always be long when the code runs. The Val function converts the first numbers it meets. Once it meets letters in a string it stops. If there are only letters then it returns zero as the value. The following code shows some examples of using Val Sub UseVal ' Prints 45 Debug. Not Multi-Region — Val does not recognise international versions of numbers such as using commas instead of decimals. Therefore you should use the above conversion functions when you application will be used in multiple regions. Converts invalid strings to zero — This may be okay in some instances but in most cases it is better if an invalid string raises an error. The application is then aware there is a problem and can act accordingly. The conversion functions such as CLng will raise an error if the string contains non-numeric characters. The first argument is the number of times to repeat it, the second argument is the character. Sub GenString ' Prints: AAAAA Debug. Print String 5, 62 ' Prints: ABC Debug. You can also use the StrConv function with the vbUpperCase or vbLowerCase argument. Print UCase s Debug. Print StrConv s, vbUpperCase ' Lower Debug. Print LCase s Debug. Print StrConv s, vbLowerCase ' Sets the first letter of each word to upper case Debug. Print StrConv s, vbProperCase End Sub Output MARY HAD A LITTLE LAMB MARY HAD A LITTLE LAMB mary had a little lamb mary had a little lamb Mary Had A Little Lamb Other Conversions As well as case the StrConv can perform other conversions based on the Conversion parameter. The following table shows a list of the different parameter values and what they do. For more information on StrConv check out the. You simply use the Split function with the delimiter as parameter. The following code shows an example of using the Split function. Print name Next End Sub Output John Jane Paul Sophie If you would like to see some real-world examples of using Split, you will find them in the post. Array to String using Join If you want to build a string from an array you can do so easily using the Join function. This is essentially a reverse of the Split function. Print sNames End Sub Output John,Jane,Paul,Sophie Formatting a String Function Params Description Example Format expression, format, firstdayofweek, firstweekofyear Formats a string Format 0. It is mostly used to place a date or number in certain format. The examples below show the most common ways you would format a date. If you want more information then the provides a lot of information. Helpful Tip for Using Format A quick way to figure out the formatting to use is by using the cell formatting on an Excel worksheet. For example add a number to a cell. Then right click and format the cell the way you require. When you are happy with the format select Custom from the category listbox on the left. When you select this you can see the format string in the type textbox see image below. This is the string format you can use in VBA. Format Cells Dialog Conclusion In almost any type of programming, you will spend a great deal of time manipulating strings. This post covers the many different ways you use strings in VBA.

For numbers, it should excel vba trim display SUM and AVERAGE. Print Mid sCustomer, 6, 6 ' Prints: Thomas Debug. Therefore if there is only one instance of the search item then both InStr and InStrRev will return the same value. Feel free to contact us again if you have any questions or need further assistance. While you can work with the inbuilt TRIM function in Excel worksheets to get rid of spaces. Print String 5, 62 ' Prints: ABC Debug. However, since we do not cover the programming area VBA-related questionsI can advice you to try and look for the solution in VBA sections on mrexcel. To prevent this from happening, you need to copy only values, not formulas.
