ISFORMULA Excel Formula
In this tutorial, you will learn the use of the ISFORMULA excel formula. ISFORMULA function in excel is useful to check whether a cell contains a function or not.
Why do We Need to Learn ISFORMULA Function in Excel?
In the data processing on a spreadsheet, sometimes we need to know whether a cell contains a formula or not. This is needed for various needs such as analyze the errors that we have in the spreadsheet or identify material for further analysis needs. If we use a manual way to see one by one the contents of our cells, then it will be very troublesome especially if there are many cells that we need to check to fulfill our needs.
As an example of this need, imagine if we find many errors in the data processing that we do on the spreadsheet. The errors can be caused by various things such as external data or formulas which are wrong in their implementation. If we know which cells contain formulas, then we might be able to do the fixes according to the appropriate needs. For that, we need to do an identification process first to check whether a cell contains a formula or not. However, if there are many cells to be identified then it will be troublesome and there will be a lot of time that we need for the identification process.
To help make the identification process much faster, you can use the ISFORMULA excel formula. ISFORMULA function in excel is useful to evaluate a cell whether it contains a function or not and give a TRUE or FALSE logic value based on the evaluation result. It is very useful to be learned and used if you sometimes need this kind of identification process in your data processing process on the spreadsheet.
