The story of CSV Lint.

One of my friend, part of his job in the company, is to receive CSV files from clients, and then import those files into an internal system. Often times, the files he received does not match the requirement, missing columns, or incompatible data types etc, he has to go back and ask his client to redo and re-send the files, he tried using Excel automate the process, but failed cause most of the files are really big (300+Mb with 1M+ rows).

There's few similar services out there, but they all require uploading files to their server, which is a big no no for my friend, no matter how secure those services claim themselves to be. That's also where CSV Lint shins the most, it process files by thunks locally in the browser, nothing goes to the "cloud".
