This time I'm posting here not to ask for help but advice.
I've developed a tool to make extremely easy data export from Elasticsearch to a CSV file, both raw and in a aggregated format.
You can find much more info at the official github page of the project.
If you wanna know what led me to develop the tool, check out my article about it.
Should you have any question about it, you can ask here, on github, email or wherever you want.
If you want to contribute to fix some imperfections, improve code and functionalities or add/request additional features, do not hesitate to raise a hand!
