💥 Developer Helpers – 19 VBA String Functions That Every Developer Will Love!

If you work with VBA, you know the drill: strings are everywhere — during import, reporting, data preparation and text processing. And every time it’s: substring here, trim there, replace over there... 😅

That ends now! 
With my new Developer Helpers you get a toolbox of 19 string functions that support you in every text task — fast, elegant and error-free.

🧩 What makes them special?

Every function is directly testable via an integrated form interface. You see the result immediately, can check your own inputs and combine functions as you like. That gives you maximum flexibility — and you work more productively, cleaner and with less debugging.

🧰 All 19 functions at a glance

✅ StringFixLength

Sets a fixed length for a text. If the string is too long it will be truncated — if it’s too short it will be padded.
StringFixLength("ABC", 6, "_") → "ABC___"

Ideal for fixed-width fields in reports or exports.

✅ StringCombine

Joins two or more strings with a freely selectable separator.
StringCombine("FirstName", "LastName", " ") → "FirstName LastName"

Perfect for names, paths or CSV formats.

✅ StringRemoveTrailingChars

Removes specific characters at the end of a text (e.g. trailing commas or spaces).
StringRemoveTrailingChars("Test, ", ", ") → "Test"

✅ StringRemoveChars

Deletes specific characters throughout the entire string.
StringRemoveChars("12-34-56", "-") → "123456"

✅ StringRemoveWords

Removes specified words from a text.
StringRemoveWords("This is a test text", "test text") → "This is a"

✅ StringExtractBetween

Extracts text between two markers — perfect for parsers or log analysis.
StringExtractBetween("Hello [World]!", "[", "]") → "World"

✅ StringCount

Counts letters, numbers, special characters or words in the text.
StringCount("ABC 123", "letters") → 3

✅ StringCapitalizeWords

Capitalizes the first letter of each word.
StringCapitalizeWords("max mustermann") → "Max Mustermann"

✅ StringCountSubstring

Counts how often a given substring occurs.
StringCountSubstring("banana", "na") → 2

✅ StringIsNumeric

Checks whether a string represents a valid number (including minus or decimal point).
StringIsNumeric("-12.5") → True

✅ StringContainsAny

Searches for any of a list of terms within a string.
StringContainsAny("This is great", Array("great", "awesome")) → True

✅ StringIsEmpty

Detects empty, null or whitespace-only strings.

StringIsEmpty(" ") → True

✅ StringExtractEmails

Finds all email addresses inside a text.
StringExtractEmails("Contact: test@mail.com or info@company.de") → Array("test@mail.com", "info@company.de")

✅ StringClean

Cleans up excessive spaces and control characters.
StringClean(" Hello World ") → "Hello World"

✅ StringRepeat

Repeats a string a specified number of times.
StringRepeat("-", 10) → "----------"

✅ StringPadNumber

Pads numbers with leading characters (e.g. zeros).
StringPadNumber(42, 5, "0") → "00042"

✅ StringWrap

Wraps long text to a specified line length.
StringWrap("This is a very long text", 10)

✅ StringToInitials 

Generates initials from names or phrases. 
StringToInitials("Max Mustermann")  → "MM"

✅ StringMaskSensitive 

Masks sensitive parts of text — shows only selected segments.
StringMaskSensitive("CreditCard1234", 4)   → "********1234"

⚙️ Deployment & Integration

All functions are commented, validate inputs and can be inserted directly into existing projects. With the test form you can try every function immediately — no setup, no add-in required. You only need the module modHelper_String. Everything else is just for testing and presentation.

🚀 Conclusion: More power for your VBA workflow

With these 19 Developer Helpers your string handling becomes faster, cleaner and much more efficient.
🔹 Less code
🔹 Fewer errors
🔹 More productivity

🧪 Try it out

Using my small testing form you can try the functions directly. This makes it easy to learn the functions step by step. Do you develop a lot with Access? Then give it a try — I’m looking forward to your feedback or ideas for additional functions! 🚀

You will find the detailed description and all instructions directly in the code - well documented as usual.
