It allows for CSV, TAB delimited, and XLSX file import and export, as well as ODS import and Markdown export. Users can customize screen colors, colorize cells, and format them with bold, italic, or underline. SC-IM supports various alphabets, sorting and filtering rows, subtotals, and clipboard support. It also offers GNUPlot interaction, LUA scripting, external functions, and non-interactive calculator capabilities. To support the development of sc-im, donations are welcome.
