I made Megarows for people who need to inspect a huge data file and quickly plot to check data quality. It opens CSV, Excel, TXT, JSON, and MATLAB .mat files locally in your browser. It’s free, doesn’t require an account, and doesn’t upload your files. I’d appreciate feedback on the first-use experience: is it clear how to open a file, choose columns, and create a useful plot? Try Megarows What would make this useful enough for you to keep bookmarked?   submitted by   /u/Winter-Arm6002 [link]   [comments]
