I need some data categorising

Industry: Technology Analysis tool: Excel Description of analysis: Hi, I need them checked against the industry sector and sub-sector (e.g. finance and banking >> global banking group) , all of which are detailed on separate worksheets - and capture any changes or missing information on the spreadsheet. The columns you'll be populating are highlighted in yellow. I've done some examples to demonstrate either how to enter a change or to keep the same. If the company no longer exists or has been acquired / merged it can be highlighted in red for deletion. The sheet is attached to give you an idea. We can check the first 10 or so records together to check you're on the right lines. Thanks Ben Extra notes:
