excel VALUE Function

The VALUE function is mainly used for compatibility with other workbook programs. Through this, you can easily convert the text string which looks like a number into a real number.

 Overall it’s helpful for fixing any type of number not only the dates.


  1. If the text string which you are using is not in the format that is well recognized by Excel then it will surely give you the #VALUE! Error.
  2. For your date Excel will return the serial numbers, so you need to set the cell format as the date for making the serial number appear just like a date.

6# DATEVALUE Function

Here is the Syntax which you need to use:


Where ‘date_text’ is referencing the cell having the date text string.


DATEVALUE is very much similar to the VALUE function. The only difference is that it can convert the text string which appears like a date into the date serial number.

With the VALUE function, you can also convert a cell having the date and time which is formatted as text. Whereas, the DATEVALUE function, ignores the time section of the text string.

7#  Find & Replace

In your dates, if the decimal is used as delimiters like this, 1.01.2014 then the DATEVALUE and VALUE are of no use

In such cases using Excel Find & Replace is the best option. Using the Find and Replace you can easily replace decimal with the forward slash. This will convert the text string into an Excel serial number.

Here are the steps to use find & replace:

  1. Choose the dates in which you are getting the Excel not recognizing date format issue.
  2. From your keyboard press CTRL+H This will open the find and replace dialog box on your screen.
  3. Now in the ‘Find what’ field put a decimal, and in the ‘replace’ field put a forward slash.
  4. Tap the ‘Replace All’ option.
