Excel coding across multiple files

I am looking for an experienced professional to help with coding across multiple files. I have approximately 1-5 files that require coding to automate a necessary task. This is a highly specific project and a high level of expertise is required. I need the work completed within more than two weeks and potential candidates must demonstrate experience in coding and automation projects. This is a great opportunity to be a part of something that has potential to make a significant difference in the project I'm working on. An ideal candidate should have an extensive background in coding and automation and be able to complete the project within the requested timeline.

Does anybody know or could develop an algorithm or simple platform (if needed) where I have two excel files and I want to "program" for example cell A10 in excel file #2 = C10 in excel file #1?
