Extracting Numeric Data from Strings in Excel

This guide provides a functional Excel formula to extract numeric data from a string, starting with the first digit and stopping at the first non-number.

Excel Formula

To achieve this, you can use the following formula:

=LEFT(A1, MIN(FIND({0,1,2,3,4,5,6,7,8,9}, A1&"0123456789", ROW(INDIRECT("1:10"))))-1)

Explanation of the Formula Components

1. FIND Function:

   • FIND({0,1,2,3,4,5,6,7,8,9}, A1&"0123456789", ROW(INDIRECT("1:10"))):
     • This part searches for each digit (0 to 9) in the string contained in cell A1.
     • The concatenation A1&"0123456789" ensures that there is a digit to find, preventing errors if no digits are present.
     • The ROW(INDIRECT("1:10")) generates an array of positions from which each digit's position will be found.

2. MIN Function:

   • The MIN function is used to find the minimum position from the previous FIND function results, which corresponds to the first digit found.

3. LEFT Function:

   • LEFT(A1, MIN(...) - 1):
     • This part uses the position found to extract characters from the left of the string in A1, up to but not including the first non-number.

Practical Example

Assume you have the following data in cell A1:

• A1: "abc1234xyz"

Using the formula provided:

=LEFT(A1, MIN(FIND({0,1,2,3,4,5,6,7,8,9}, A1&"0123456789", ROW(INDIRECT("1:10"))))-1)

Result: The output will be "" (an empty string) as there are no digits before the letters.

If A1 were instead:

• A1: "Price is 456 dollars"

Then applying the formula would yield:

Result: 456

Conclusion

This formula effectively extracts all characters starting from the first digit in a string until it encounters a non-digit character. It can be adjusted for various contexts and ensures that even if there are no numbers, it will gracefully return an empty string.
