This tutorial will demonstrate how to convert a text string to a date in Excel and Google Sheets.
Convert Text String to Date
If you have a date in Excel stored as text, you will not be able to use the date in any calculations. However, you can convert a date stored as text to an actual date in Excel by using the DATEVALUE Function.
Dates in Excel are stored as a value representing the number of days since the first day of Excel.
The first day of Excel is the imaginary date of January 0, 1900. So the date 05/08/1995 is stored as the number 34,916.
To display the serial number as a date, simply change the number formatting to date.
The VALUE Function will work in the same way
Convert Text ‘yyyymmdd’ to Date
There might be a time that you need to convert a number or a text string in the format ‘yyyymmdd’ to a date. To do this, you will need to use the DATE function, in conjunction with the LEFT, MID and RIGHT Functions.
=DATE(LEFT(B3,4), MID(B3,5,2), RIGHT(B3,2)
The LEFT Function
The LEFT function will return characters on the left of your text string, in this case we have selected to return 4 characters.
The MID Function
The MID Function will return middle characters in your text string. The starting middle character is indicated by the second argument (eg: 5), and the length of the string is indicated by the third arguments (eg: 2).
The RIGHT Function
The RIGHT function will return the characters to the right of your text string, in this case we have selected to return 2 characters.
