A cross-platform editor for .csv files
This feels like Markdown for spreadsheets: SmoothCSV is a cross-platform app made by kohii, which allows to comfortably edit .csv files.
.csv files are text files that can be created, read, and shared with any tool capable of handling text. SmoothCSV can pick up and create .csv files with a comprehensive editing experience – on Mac and Windows. SmoothCSV is fast, probably because it´s written in Rust. kohii explains how he created the tool in his dev.to article The Technology Behind SmoothCSV - The Ultimate CSV Editor.
