4. Force to Return Numbers Applying Excel LEFT & VALUE Functions
We can fetch numbers from text. The string we store, usually are in text format. We can fetch the digit value from the string and convert them to a number.
Our example dataset contains several IDs for employees.
The first 3 characters are digits. We will fetch these 3 characters as a number. The VALUE function will be useful for our operation.

Steps:
- Firstly, select Cell C5 and type the following formula.
=VALUE(LEFT(B5,3))- Next, press Enter and drag down the Fill Handle tool.
🔎 How Does the Formula Work?
- In the beginning, The LEFT function returns the first 3 characters from the ID.

Things to Remember
- If we provide a value less than 0 into the num_chars field, then it will provide #VALUE! Error.
- Secondly, for dates, you may not find the exact value you are wanting. From a date, if you want to find the day portion, you may write LEFT with 2 in the num_chars field. But will find another value, not the day value of the provided date.
- Usually, Excel stores dates as sequential serial numbers. 1 January 1900 is the 1st date, and its serial number is 1. From there every date has its subsequent serial number. Thus, the functions convert dates to their respective serial number before doing the operations.
- Therefore, if you set the cell containing the date into General you will find the serial number. The formula will extract from that serial number.
- Finally, you can also provide the text value directly into the function.
