To import very large CSV files, you can use the bench utility `import-csv`. The benefit is that this is not subject to timeouts if you use the web interface. Here is an example: bench --site test.erpnext.com import-csv ~/Downloads/Activity_Type.csv ### Help $ bench import-csv --help Usage: bench import-csv [OPTIONS] PATH Import CSV using data import tool Options: --only-insert Do not overwrite existing records --submit-after-import Submit document after importing it --ignore-encoding-errors Ignore encoding errors while coverting to unicode --help Show this message and exit.
