Extracting Text with LEFT, RIGHT, MID

Pyyhkäise näyttääksesi valikon

Sometimes you don't need to split the entire text into columns. Instead, you may want to extract only a specific part of a value. This is very common when working with structured text like product codes, IDs, or formatted strings.

For example, a product code like PRD-001 contains two parts: a prefix (PRD) and a number (001). Instead of splitting everything manually, you can extract exactly the part you need using functions.

LEFT, RIGHT, MID Functions

Excel provides three functions for extracting text:

  • LEFT → extracts characters from the beginning;
  • RIGHT → extracts characters from the end;
  • MID → extracts characters from the middle.

If a cell contains:

"PRD-001"

Then:

=LEFT(A2, 3) → "PRD"
=RIGHT(A2, 3) → "001"
=MID(A2, 5, 3) → "001"

=LEFT(A2, 3) returns the first 3 characters from the beginning of the text, =RIGHT(A2, 3) returns the last 3 characters from the end, and =MID(A2, 5, 3) extracts 3 characters starting from position 5 in the string.

Task

Create two new columns: Product Prefix, Product Number

Extract:

  • The first part (PRD) using LEFT;
  • The numeric part (001) using RIGHT or MID.

Apply the formulas to all rows.

Note
Hint

Use =LEFT(D2,3) for the prefix and =RIGHT(D2,3) or =MID(D2,5,3) for the number, then apply the formulas to all rows.
