Pixel Spreadsheet
This is a recreation of Matt Parker's image-to-spreadsheet online spreadsheet generation software.
This version uses exceljs and HTML canvas to convert images into Microsoft Excel spreadsheets. No images are sent to any external servers, as processing is all done on your computer.
For more context, watch Matt's video about this here: Stand-up comedy routine about Spreadsheets
