Understanding Excel’s Text Functions for Replacement
Before we jump into the tutorials, let’s get familiar with the functions we’ll use.
Overview of Key Functions
REPLACE Function Basics
Use it when you know where the characters you want to replace are positioned.
SUBSTITUTE Function Basics
Perfect when you need to replace specific characters or words based on matching text.
TEXTAFTER & TEXTBEFORE (Excel 365)
Ideal for restructuring sentences, extracting words, and replacing text dynamically.

1. Using the REPLACE Function to Update Characters Precisely
If you want to replace characters based on position, REPLACE is your best friend.
Syntax:
=REPLACE(old_text, start_num, num_chars, new_text)
Syntax and Practical Examples
Example: Replace the first three characters of a code.
=REPLACE("ABC123",1,3,"NEW")
Result: NEW123
This is perfect for SKU adjustments, ID updates, or formatting codes.
For more formula guides, see Excel Formula Tutorials.
2. SUBSTITUTE Formula Tutorial for Replacing Exact Words
If you want to replace words instantly, this should be your go-to.
=SUBSTITUTE(text, old_text, new_text)
Replace One or All Occurrences
Replace only the second occurrence:
=SUBSTITUTE(A1,"apple","orange",2)
This is extremely useful when cleaning repeated product names or messy imports.
3. Combining REPLACE & LEN to Swap Word Endings
Want to replace the ending of a word regardless of length? Use:
=REPLACE(A1, LEN(A1)-2, 3, "ing")
This replaces the last three characters with “ing.”
It’s a great trick for making plural/singular formatting automatic.
4. Remove Unwanted Characters with SUBSTITUTE and CHAR
Invisible characters often sneak into imported datasets.
=SUBSTITUTE(A1,CHAR(160),"")
CHAR(160) is a non-breaking space that ruins sorting and filtering.

5. Replace Line Breaks Using CHAR(10)
Ever paste text from Word and end up with ugly line breaks?
=SUBSTITUTE(A1,CHAR(10)," ")
This instantly converts line breaks into spaces so your text aligns perfectly.
6. Replace Words in Bulk Using Nested SUBSTITUTE
Need multiple replacements at once? Just stack them:
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,"blue","red"),"old","new"),"XL","Large")
In one formula, you can transform several words.

7. Using TEXTAFTER + TEXTBEFORE to Restructure Phrases
Excel 365 users get a powerful combination:
=TEXTBEFORE(A1," ")-"NEW "+TEXTAFTER(A1," ")
This can rearrange words dynamically.

8. Flash Fill for Instant Pattern-Based Replacement
Sometimes formulas aren’t even needed.
Just type the corrected text in the cell beside your data, press:
Ctrl + E (Flash Fill)
Excel will detect patterns and auto-replace the rest.
This is ideal for email formatting, names, and ID codes.
9. Advanced Power Query Replace Transform
For massive datasets, Power Query is the superior choice.
You can:
- Replace multiple words
- Remove symbols
- Strip prefixes and suffixes
- Standardize casing
Power Query ensures transformations repeat automatically.

10. Replace Entire Patterns Using Excel 365 LAMBDA
Want your own custom replace function?
=LAMBDA(text,old,new,SUBSTITUTE(text,old,new))
You can store and reuse this like a built-in function.
This is especially useful for heavy automation—great for Excel Automation and Workflow Automation.
