Hourly Data Truncation

I have mostly dealt with monitored hourly ozone data before. I am trying to enter in hourly PM2.5 data and it is more important to get the whole year in. I am having an issue where the csv is getting truncated after 32,767 characters so some of the hourly data gets dropped to the next line. I did a search and replace to get rid of extraneous zeroes in the string, but still too long.

Any advice on how to get the data into BenMap so I can do a rollback analysis?

Also if I have to hack it to get it to work, any chance this can be fixed in future iterations?
