Hi there i've read your descriptive and understand that you want to retrieve details against ISBNs from an excel sheet in excel file in turn. I've already worked with programmatically generating, reading and modifying excel files. My last project at S&P Global was exactly of the same nature. I had to fetch data from Microsoft Azure APIs and generate excel reports for employees in a certain format. I will use C# and the .NET framework, Moreover I can work without using COM interop services which means I can make the script work on PC, Mac, Linux and even on your Phone!.
Let me give you a glance of what I'll do for you:
1) Write the basic code that helps with communicating with Amazon API.
2) Write code that allow (CRUD) operations on excel files.
3) Create an easy to use UI to help you operate the program easily.
4) Test and make sure everything works or do any changes you require.
I can't write everything in detail here, so let's have a discussion soon!.
For my experience. I've been programming for 2 years now, have worked on a few solo projects as well as a project in an indie game studio. You can check out my work here:
