AddMaple can read large data files - including files that will crash a spreadsheet.
On a modern computer AddMaple can easily read in data files of up to 200MB with millions of rows of data. If your data is larger than this then AddMaple may still be able to read the data but it will depend on how much memory your computer has.
AddMaple uses a custom column-based in-memory store to allow instant access and analysis of your data, but this requires loading the entire file into memory. This approach works remarkably well for a wide range of data analysis tasks.
