���ճԹ�’s ETL Helper software tool is a package for the Python programming language. Version 1 includes driver updates and usability improvements; however, the most significant change is the addition of a documentation website. This will make the software more accessible and expand the pool of users and potential contributors.

Since ETL Helper was released as open-source software in 2019, it has picked up a global user base, with users from Columbia to Kenya, India to China as well as North America and Europe. It is downloaded over 25 000 times per month and has received code contributions from as far away as Australia.

ETL Helper was created because common proprietary data-transfer tools were difficult to use in a team setting. I always thought that the data-transfer tasks we were doing should be simple to write in Python. However, once you add in database connection setup, error handling and memory management, the reality was more complicated. ETL Helper takes care of this and allows us to transfer the data using only a few lines of code.

Open-source software allows users to inspect how the software works and modify it to suit their needs. In a scientific context, using open-source software allows collaborative software development with partners and the wider community. ETL Helper is one of the many software outputs that are released by ���ճԹ� under open-source licences. Others include utilities for plotting maps of volcanic of ash clouds, validating borehole log data and selecting target points on samples for microanalysis.
