I am seeking for someone to help me clean up and tidy 3 years (2010 - 2012) of Excel file.
The files contains customers details.
I need to remove all duplicates in the spreed sheets, arrange the contact number of my customers in order, removing invalid contact numbers, removing the spaces in between the contact numbers.
There are a total of approximately 85000 (including duplicates) data in the spreed sheets.
It should be a breeze for those proficient in Excel.
