Hi,
I'd like to discuss the project with you.
After that I will know more possible essential details, and I could definitely update my bid accordingly :)
By the way, I hope you know about the Google Sheets does provide a saving of a table as a PDF file right now, as an at present option...
Well, PROBABLY, you should upload your Excel table into Google Sheets simply, and then save it as a PDF...
No problem though, in a case if you'd like a standalone app (for security etc), in such case I could develop and implement a Windows app on C# for instance, there are various and affordable .NET libraries and ready-to-integrate modules for such kind of conversions. So, too many things depend on details, as regular, and specific of your tables may be matter as well...
Let's discuss.
Regards.
