Excel VBA Macro Functionality Enhancement

Need an experienced freelancer to improve an existing macro-driven Excel worksheet by adding new functionality and refining current processes. The work includes updating formulas, improving automation, and making the spreadsheet more efficient and user-friendly. The existing sheet imports client data from a multi-tab source workbook and organizes it into several tabs with specific formatting. Each tab can be exported to an individual CSV file for upload to our processing software. The project involves adding tabs to the import file so that additional csv files are created. You should be comfortable working with complex spreadsheets and delivering reliable, well-documented solutions. Please share relevant experience with similar Excel automation projects.
