multiple attributes in csv file to raster

[المشرف العام]

I have a several large comma separated text files each with multiple attributes. Each text file is about ~2.9 GB with 21 million lines. Each line contains X, Y, VALUE1, VALUE2, VALUE3, etc. The X and Y for each row represent the centroid of a regular grid (50m) while the values are results generated from a simulation.

Current workflow (in ArcGIS):

1. Convert csv file to XY EventLayer (time consuming for large files)
2. Export each attribute as a separate raster using the Point to Raster tool.

My question: is there a faster/easier way to convert a text file with XY and multiple attributes into separate rasters?
