Hi there!
I've read you requirements. It seems you are looking for a C#/.NET developer who can help you automate processing of an excel sheet with formulas in C#. I can help you with that
I am a full stack .NET developer. I have worked on projects that used to deal with complex data and that data would be imported from excel sheets and involved processing on our end. I am well versed in developing web solutions in ASP.NET Core, MVC, Web API, Angular 6+, Azure, TypeScript, SQL Server, Entity Framework, EF Core and Dapper.
If any of this sounds interesting, please reply to this and we can arrange to discuss your requirements in detail.
Best regards,
Divyansh Bhatia
