Data Cleaner

We have a large amount of data in a spreadsheet that contains many duplicate records. Your task is to work with me to remove all of the duplicate data. You must be an expert with Microsoft Excel and/or Google sheets.

For now this is just a one-time gig but could eventually 7lead to full time employment.

Please send me an example of a complicated spreadsheet that you have worked on in the past.

regards
Jim Donovan
