A print helper. Upload a workbook, choose how it should print, then download a corrected Excel file or a ready-to-share PDF. It never changes your data, values, formulas or cell formats: the corrected Excel file is your own file with only print settings, column widths, row heights, text wrapping and borders edited, and the app proves it by comparing every cell with your original. Everything runs on your own device, so your file is never uploaded anywhere.
The page-by-page preview, the PDF download and the corrected Excel download are the next steps of this build.
Nothing is uploaded. Everything happens in this browser, and the page makes no network requests once it has loaded.
