Software that I developed for reading the nda file format from Neware battery cyclers is now an open-source project on Github. It’s a tool that I developed as a side project at work that turned out to be a much better alternative than manually exporting to Excel and then read into Python. I’ve also included a command-line tool which can convert nda directly to a variety of other formats without having to write any code. I had the benefit of being able to test against a large number of nda files from different generation cyclers, which I hope has resulted in robust code.
