Load multiple csv files together and at once

[zs1992]

Hi everyone,
I'm trying to load multiple csv files(over 200) at once, so I could write
the whole data to Netcdf files.
Since the csv files are mixed with numbers, date strings and column names, I
can't use csvread or dlmread, otherwise I get weirdly-arranged data. I also
tried dataframe, but it takes 28 seconds to read a csv file, which is way
too time-consuming.  
Currently, what works for me is csv2cell, which converts a csv into a cell
array. However, the csv files I have have different numbers of columns(also
different column names). Therefore I can't concatenate them into one big
cell array.
Is there any good solutions to that?
Best regards,
Shuo
