SmoothCSV is a cross-platform CSV editor built for real work. Edit your files intuitively, exactly how you want. Lightning-fast performance, handles messy data, and powerful features like SQL queries. Just smooth CSV editing that works.

My aspiration is for this app to eventually be considered the "VS Code of tabular editors."
