The LEFT function in Excel is a powerful tool for extracting characters from the beginning of text strings. Whether you need to parse names, format product codes, or clean up data, understanding how to use LEFT effectively can save hours of manual work. Let’s explore how to use this function through practical examples and common scenarios.

Extract Characters from the Left Side of Excel Cells

Basic LEFT Function Syntax

LEFT(text, [num_chars])

Where:

• text: The string you want to extract characters from
• num_chars: The number of characters to extract (optional, defaults to 1)

Step 1: Extract a specific number of characters

1. Open your Excel spreadsheet
2. Select the cell where you want the result
3. Enter the LEFT function with your parameters
4. Press Enter to see the result

Example:

Step 2: Use cell references

1. Replace hard-coded text with cell references
2. Adjust the number of characters as needed
3. the formula to adjacent cells if necessary

Example:

Remove Characters from the Beginning of Text

Sometimes you need to remove rather than extract characters. Here’s how to accomplish this using LEFT with other functions.

Step 1: Determine text length

1. Use the LEN function to find total character count
2. Subtract the number of characters you want to remove
3. Combine with LEFT function

Example:

Extract Text Before a Specific Character

One of the most practical applications is extracting text before a particular character or delimiter.

Step 1: Combine LEFT with FIND

1. Use FIND to locate the delimiter
