How to Use SUBSTITUTE for Data Cleaning | Excel string functions - PART 3
Following Part 1 and Part 2, where MM Technology focused on extracting data using LEFT, RIGHT, MID, LEN, and FIND, we are moving to the next step in our series.
In Part 3 of our "Comprehensive Excel String Functions" series, we will explore the SUBSTITUTE function—a powerful tool for modifying and restructuring content.
Instead of manually using "Find & Replace" for every individual case, you will learn how to build formulas that automate bulk changes with absolute precision.
Key applications of SUBSTITUTE in this video:
📌 Standardizing Formats: Seamlessly change separators (e.g., "." to "/") in dates or order IDs.
📌 Data Cleaning: Remove redundant spaces, special characters, or common typing errors.
📌 The "Instance_num" Power: Learn how to replace specific occurrences (e.g., only the 2nd dash) instead of the whole string.
📌 Formatting Identifiers: Quickly unify phone numbers and IDs by removing parentheses or dashes.
