In this SharePoint tutorial, I will show you how to convert a text string that stores numbers to number values in SharePoint calculated column using the VALUE function.
The VALUE function converts numbers in a text format to number values. If a text or choice column has text characters instead of numbers, the values will not be displayed; It will show an error as #VALUE! in a calculated field.
