Zipadee lets you quickly view the contents of a ZIP file, edit the files, then export an updated ZIP file.

A couple of weeks ago I decided to make a web app (a PWA, in fact, so it can be installed and works offline) to make it easy to look inside ZIP archives and make changes to files, without having to manually unzip, edit, then re-zip the contents. As a bonus, Zipadee can read any kind of ZIP archive, so you can look inside Office files (DOCX, PPTX, XLSX) or EPUB files and use the image preview feature to explore the contents. The editor is the open source Monaco Editor, as used in VS Code, so it provides syntax highlighting and other editor features for most common languages.

Cool project! Very handy to peek inside a zip. Can you also link to the source? I'd like to take a look.
