Hi,
It's very clear what's required from your job description and I think it's very achievable.
My experience in Visual Basic & Excel knowledge more than covers your requirements.
My Excel & VB experience extends to writing custom Excel functions, consolidation of multiple workbooks, CSV exports, API calls, XML parsing, complex actuarial calculations, data analysis... so formatting your CSV should be fairly straightforward!
As to why else to hire me, as well as having strong abilities in Excel & Visual Basic, as a native English speaker & business professional, my ability to communicate clearly is excellent. That comes into use when ensuring I capture your specification correctly, understand your requirements and can deliver a quality outcome.
Also, just FYI, I noticed someone has duplicated your job description so you might want to be wary of anyone being awarded the job and then getting someone else to do it:

Thanks and, if you have any further questions, please let me know.
