Alternatives

There are several other packages for reading CSV files in Julia, which may suit your needs better:

• The standard library contains DelimitedFiles.jl, at least until Julia 1.8. This returns a Matrix rather than a Tables.jl-style container, thus works best for files of homogeneous element type. On large files, CSV.jl will be much faster.

• CSVFiles.jl uses the FileIO.jl's load / save API, but otherwise has similar goals. Like CSV.jl, it works with Tables.jl objects such as DataFrames.

• DLMReader.jl also aims to be fast for large files, closely associated with InMemoryDatasets.jl.

• Pandas.jl wraps Python's pandas library (using PyCall.jl). This is a closer cousin of DataFrames.jl, but builds in the ability to read/write CSV files.
