Convert many large TDMS files to CSV files

Hi, I'd like some help with my problem.

I have 200ish TDMS files of 200MB each, and would like to convert them to CSV or another file system which I would be able to import it on python/R/Lua.

 

I managed to find a solution using Write to Spreadsheet File on a for loop, but the csv files don't have header, are transposed (2xN instead of Nx2) and give me no time column.

So I am using now Export Waveforms to Spreadsheet File, which gives me the output I am expecting (with header, Nx2 and time information), the problem is that it is giving me the error "Memory is full". I have 20GB of memory RAM and 60GB of virtual memory on Windows 7 64bits, so I don't actually understand how it happens.

 

Does someone know how to copy large TDMS files to CSV files (or anything that Python/R/Lua can read)? (I need files for those languages because this data is going to be used on machine learning algorithms by people that does not have NI licenses).
