Then ask your agent:
“Convert the NC files in my Downloads folder to ARROW”
Or run it yourself:
filestarcli -i file.nc -c "convert to arrow"
Runs on your computer, so your files stay on it. Works on Windows, macOS and Linux. 50 free conversions with the npm install, no account needed.
Can my AI agent convert NC to ARROW?

A NetCDF file stores scientific array data (climate, ocean, remote sensing) with named dimensions, coordinate variables, units and metadata. NetCDF-4 files are HDF5 containers.
An Arrow IPC file holds a data table in Apache Arrow's in-memory columnar layout, so it can be memory-mapped and read without conversion. Feather version 2 files are the same format.
