I am currently evaluating dsq and its partner desktop app DataStation. AIUI, the developer of DataStation realised that it would be useful to extract the underlying pieces into a standalone CLI, so they both support the same range of sources.
qsv is a fork of this, as qsv is pretty much unmaintained now (I don't mean to sound negative, BurntSushi did an AMAZING job and I love the work they did).
I’ve spend what feels like too much time looking for a windows app that I can use to occasionally preview CSV files before moving them into WSL.
I just think $50/year is too much for occasional use.
Since this posts has initiated several other shameless plugs, maybe I can swoop in and ask for shameless recommendations for something cheap in this space.
This one is another desktop app, with a slightly different approach: in the CSV file case, the data is parsed and dumped into a bundled PostgreSQL database, which you can then query with a visual query interface.
dsq CLI - https://github.com/multiprocessio/dsq DataStation desktop app - https://datastation.multiprocess.io/
Two alternative CLI tools that I looked at:
sq - https://sq.io/ octosql - https://github.com/cube2222/octosql
Honourable mentions to:
Miller - https://miller.readthedocs.io/en/latest/index.html Dasel - https://daseldocs.tomwright.me/
These don't use SQL.
VisiData is also amazing for data navigation, although it requires some effort to get the model:
