Cassava
Still plugging away on Cassava, a CSV editor that sits somewhere between sublime text and Excel: https://cassava.dev/. Our most recent releases added first-class xls/xlsx file opening and an autofill handle. The project goals are simple: * Treat CSV files like first-class spreadsheets; don't do anything that isn't supported by serializing to/from CSV files * Be as performant as your favorite text editor while retaining the ergonomics of a tabular data editor I hope you check us out.
