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

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.
