The Fastest Way To Convert Numbers Stored As Text To Numbers & Dates

Get Rid of Numbers Stored As Text Error in Microsoft Excel

What This VBA Code Does

I have always hated the time it takes to convert text to numbers, especially on large database exports.  That's why I was ecstatic to find a VBA solution that speed up text conversion from minutes into just a few seconds.  The solution was written by Ejaz Ahmed of Struggling to Excel.  He was gracious enough to allow me to share his code with you all and I really think you will be blown away with it's capabilities.

Ejaz's code does much more than just convert text to numerical values.  It also trims the selected data (deleting any trailing or preceding spaces in your values) and converts text to dates.  The code does all of this at the exact same time!  It's really powerful!!

I went ahead and rewrote the code to align it with the VBA coding style of this blog.  If you're curious or want to ask Ejaz a question you can view his original code and blog post, Do You Hate The Numbers Stored As Text Error. Make sure you add both the subroutine and function to your code module. Enjoy!
