How to Automate App Store Localization for 47 Languages in Minutes
Learn how to automate iOS App Store localization using our Chrome extension. Fill Name and Subtitle fields for all 47 locales in 10-15 minutes instead of hours.
The Problem with Manual Localization
If you've ever localized an iOS app for multiple markets, you know the pain:
- 📝 47 localizations × 2 fields = 94 manual copy-pastes
- ⏰ 2-3 hours of tedious work per app update
- 😫 High risk of typos and inconsistencies
- 🔄 Repetitive switching between languages and waiting for page loads
There has to be a better way!
The Solution: Chrome Extension + JSON
We built Store Localization: ASO Auto Fill, a Chrome extension that automates the entire process. Here's how it works:
Step 1: Prepare Your JSON File
Create a simple JSON file with all your translations:
{
"en-US": {
"name": "English Verbs: Right Way to B2",
"subtitle": "irregular verbs pictures & quiz"
},
"ru": {
"name": "Англ. глаголы: учим A2 B1 B2",
"subtitle": "Неправильные глаголы: тесты"
},
"de-DE": {
"name": "Englische Verben: Weg zum B2",
"subtitle": "Unregelmäßige Verben: Bilder"
}
// ... 44 more locales
}
Step 2: Navigate to App Information
- Open App Store Connect
- Go to General → App Information
- Select any locale from the dropdown
The extension automatically detects you're on the right page!
Step 3: Click Run Button
That's it! The extension will:
- ✅ Fill the Name field
- ✅ Fill the Subtitle field
- ✅ Click Save button
- ✅ Switch to next locale
- 🔁 Repeat for all 47 locales
Total time: 10-15 minutes!
