Create 1000 Rows and Columns in Microsoft Excel and create Multiple Data in Microsoft Excel need to complete this project in 1 week

I am looking for someone to help me create 1000 rows and columns in Microsoft Excel and fill them with multiple data. Whether I will need to use a formula for the data depends on a case-by-case basis and I need the data to be collated or structured in a particular way, which can be determined during the project. Also, whether I need special formatting for the cells may depend on the context of the project. I would like an Excel expert who has experience dealing with large datasets and is familiar with the nuances of formatting, syntax and formulae. Experience with VBA coding would be a big bonus – any developer who can provide this will be highly considered.
