Wow, that is a nice little tool. Just installed it and tested on some random files in my current data analysis project.
By the way, I installed it using pipx https://github.com/pipxproject/pipx by running `pipx install visidata`. To also read HDF and Excel files, I added the necessary packages by running `pipx inject visidata h5py openpyxl`.
Thanks @rasmusei! If you are a data scientist you might also be interested in how to work along with Jupyter. Our community has some documentation on our Wiki about that here: https://github.com/OpenRefine/OpenRefine/wiki/Jupyter
You can use python code for more advanced data manipulations and creating plugins.
