Excel LEN Function
In this tutorial, you will learn about how to use LEN function in excel. Excel LEN function is useful if you need help on knowing how many characters are there in a data or cell content in your spreadsheet.
Why We Need to Learn About LEN Function in Excel?
Special condition in a data sometimes needs maximum length restriction for the data it can be processed correctly. If the length exceeds the maximum restriction, then the data can be considered as invalid and cannot be processed because of the limit of character amount per data entry which must be held for the processing.
For example in work, imagine if we are working on variables in the spreadsheet tool with the database that we get from online and we can identify the valid or invalid variables based on the length. If the amount of characters in the variable is not normal and very long, then we can group the data to invalid. The valid variable has the normal amount of characters in it.
To help to calculate the number of characters in a data or cell content, you can use excel LEN function. By using it, the calculation work can become much faster because LEN function in excel is pretty easy to use for a formula in this spreadsheet software and also the automatic nature of its calculation process also helps. You can also easily copy from one of these formulas to do a calculation in the other cell, making it easy to process calculation of many data at once.
What is Excel LEN Function?
Excel LEN function is a formula to calculate the length/amount of characters from a data or cell content. Often the result of LEN function in excel is combined to become the input for condition evaluation material of other formulas in this spreadsheet software. It is seldom that we use the result directly without any further processing.
Brief explanation about the input in the formula is:
=LEN(text)
Note:
text = the data that you want to see the amount of characters in
How to Use LEN Function in Excel?
The next part will explain how to use the excel LEN function. LEN function in excel only needs the input of data or cell coordinate for the counting process of how many characters are in it.
Using Excel LEN Function

Type equal sign ( = ) in the cell where you want to put the result in

Type LEN (can be with large and small letters) and open bracket sign after =

Type data or cell coordinate where the content that you want to process is in, after open bracket sign

Type close bracket sign
 Press Enter

The process is done!

Additional Notes
 Space is also counted in this formula calculation process
 Because the result is just the length of characters in a data or cell content, then often this formula is combined as input for condition evaluation of other formulas in this spreadsheet software.
