Oct 29, 2024
Do you need to clean up unwanted characters from the start of a cell in Excel?
Whether trimming extra spaces or removing specific text, you need to get your data right for efficiency. Luckily, AI tools can help you automate this data-cleaning task.
In this article, we’ll show you how to use Excel functions and AI to efficiently remove characters from the left side of a text string.
How To Remove Characters From Left Excel Using AI
You don't need to master Excel functions to remove characters from the left in your cells. With tools like ChatGPT and Perplexity AI, you can instantly generate formulas or scripts based on your needs.
Method 1: Asking for a formula.
An easy way of removing characters from your cells is to generate a formula with AI. These tools are easy to use.
Step 1: Open ChatGPT or your AI tool.
Start by launching ChatGPT or any AI tool you prefer.
Step 2: Use the following prompt.
To remove characters from the left, use this prompt:
Prompt example:
"Generate an Excel formula to remove the first 5 characters from cell A1."
Step 3: Copy the AI-generated formula.
ChatGPT will provide the following formula: =RIGHT(A1, LEN(A1) - 5)
This Excel formula automatically calculates the length of the text in cell A1, subtracts 5 characters, and returns the rest of the string.
Method 2: Using a VBA code.
For more complex scenarios, you can ask AI to generate a VBA script to automate this task across multiple cells.
Step 1: Use the Following Prompt
Prompt Example:
"Can you generate a VBA script that removes the first 3 characters from every cell in column A?"
Step 2: Paste the Script in Excel
ChatGPT will generate a VBA script like this:
Sub RemoveLeftChars()
Dim cell As Range
For Each cell In Range("A1:A100")
cell.Value = Right(cell.Value, Len(cell.Value) - 3)
Next cell
End Sub
This script removes the first three characters from every cell in the range A1. You can modify the range and number of characters as needed.

How To Remove Characters From the Left Using Excel Functions
Excel provides several built-in functions to help remove characters from the left of text strings. The most commonly used methods involve a combination of the LEFT, RIGHT, and LEN functions. Here’s how they work:
1. Deleting the first character in a text string.
Combining the RIGHT and LEN function is a straightforward way to remove the first character from a string.
Formula:
=RIGHT(A1, LEN(A1) - 1)
Explanation:
-
LEN(A1) calculates the total number of characters in the string within cell A1.
-
Subtracting 1 removes the first character.
-
RIGHT(A1, LEN(A1) - 1) extracts all characters from the right side, except the first one.
Example:
-
Original text in A1: "Hello"
-
Formula: =RIGHT(A1, LEN(A1) - 1)
-
Result: "ello"
2. Deleting characters in a text string.
You can use the REPLACE function to remove a specific number of characters from the start of a text string. It deletes characters from the left by replacing them with an empty string.
Formula:
=REPLACE(A1, 1, X, "")
Explanation:
-
A1: The cell containing the text.
-
1: The starting position (this indicates to start replacing from the first character).
-
X: The number of characters you want to remove from the left.
-
"": This represents replacing the removed characters with nothing (an empty string).
Example:
-
Original Text in A1: "12345Text"
-
To Remove First 5 Characters:
=REPLACE(A1, 1, 5, "") -
Result: "Text"
If you want more flexibility, the MID function allows you to specify the starting position of the substring you want to keep.
Formula:
=MID(A1, X+1, LEN(A1))
Explanation:
-
X+1 tells Excel to start extracting from the position after the first X characters.
-
LEN(A1) defines the total length of the string, ensuring it extracts everything after the removed characters.
Example:
-
Original Text in A1: "12345Text"
-
To Remove First 5 Characters:
=MID(A1, 6, LEN(A1)) -
Result: "Text"
