What is apple-storeconnect-metadata-filler?

Apple Store Connect Metadata Filler is a Chrome extension for iOS app developers who submit apps in many languages. App Store Connect requires you to manually paste in fields like Promotional Text, Description, What's New, and Keywords separately for each supported language, so an app localized into 15 languages means around 60 manual copy-paste actions every time a new version goes out. This extension removes most of that repetitive work. The extension can pull metadata from your app's previous published version, copying the Promotional Text and Description for every language automatically. You can also type in translations once for each language and save that set so it can be reused the next time you submit a version. A one-click Apply All button then writes the saved text into every language's fields on the submission page at once, with checkboxes to control which fields get filled. Other features include live character counters for each field so you can see how close you are to Apple's limits, a way to copy one language's text to all the other languages at once, keyboard shortcuts for moving between languages and applying changes, and the ability to export and import saved translation sets as JSON files. Saved sets are tied to the specific app they were created for, so switching between apps will not accidentally load the wrong data. Installing it means cloning the repository, generating the extension's icon files by opening a small HTML page in Chrome, then loading the folder as an unpacked extension through Chrome's developer mode, since it is not distributed through the Chrome Web Store. The extension only requests the browser permissions it needs to read and write the current App Store Connect tab and to store your saved translations locally. According to the README, no data is sent anywhere outside your own browser. It supports all 50 languages available on the App Store and is released under the MIT license.
