What does it do?
Replaces part of a text string, based on the number of characters you specify, with a different text string
=REPLACE(old_text, start_num, num_chars, new_text)
What it means:
=REPLACE(this cell, starting from this number, all the way to this number, with this new text)
I had a scenario where I wanted to extract the last names from a list of names using a formula.
Did you know that we can creatively use the Replace formula to replace the first name with an empty string, leaving us with the SURNAME?
Here is what we want to happen:
I explain how you can do this and please go to the bottom of the page to see the animated gif tutorial:
STEP 1: To start off, let us try the Search function and see what it will give us. We want to search on which character the space resides on. Type in:
=SEARCH(” “, C11)
You will see that it returned 6.
This means our space is on the 6th character of the name Talon Ferguson.
We will use this in our Replace function later in STEP 3.
STEP 2: Clear the Search function. We need to enter the Replace function next to the cell that we want to clean the data from:
STEP 3: The Replace arguments:
Which text do we want to change?
Reference the cell that contains the text string:
Which character do we want to start the replacement from?
We want to replace the first name, which resides on the first character:
How many characters do we need to replace?
We don’t have the exact number of characters, so this is where the SEARCH function comes in handy from STEP 1 above.
Search for the space character ” “ which tells us the end of the First Name:
=REPLACE(C11, 1, SEARCH(” “, C11),
What text will serve as the replacement?
Now that we have accounted for all the characters from the First Name, we need to clear these.
We can do this by replacing it with an empty string.
This will “erase” the First Name, and leave us with the Last Name.
=REPLACE(C11, 1, SEARCH(” “, C11), “”)
STEP 4: Do the same for the rest of the cells by dragging the REPLACE formula all the way down using the left mouse button.
Now we have all of the last names:
