What This Workflow Does

Managing iOS app localization across multiple languages is a complex process that often leads to translation gaps between your source .strings files and translation spreadsheets. This workflow solves the synchronization challenge by automatically identifying missing translations between your iOS localization files and Google Sheets, then creating GitHub pull requests with placeholder markers for translators.

The automation eliminates manual comparison work that typically consumes hours of developer time during each localization update cycle. It ensures no translation keys fall through the cracks while maintaining proper version control through GitHub PRs that translators can directly work from.

How It Works

1. Extract iOS .strings file contents

The workflow begins by parsing your iOS .strings files to extract all localization keys and their base language values. It handles both standard and pluralized string formats while maintaining proper encoding for special characters.

2. Compare with Google Sheets translations

Next, it connects to your Google Sheets translation spreadsheet and compares the existing translations against the keys found in the .strings file. The system identifies any keys missing translations for any supported language in your localization matrix.

3. Generate GitHub PR with placeholders

For all identified gaps, the workflow creates a new GitHub branch and generates properly formatted .strings files with placeholder comments where translations are missing. It then opens a pull request with clear instructions for translators to fill in the gaps.

Who This Is For

This workflow is ideal for mobile development teams managing iOS apps with multiple language localizations. It's particularly valuable for:

  • App developers coordinating with external translation teams
  • Product managers overseeing multilingual app releases
  • Localization specialists managing translation workflows
  • DevOps engineers streamlining CI/CD pipelines with localization checks

What You'll Need

  1. An n8n instance (self-hosted or cloud)
  2. Access to your iOS project's .strings files
  3. Google Sheets with translation management setup
  4. GitHub repository access with push permissions
  5. Google Sheets API and GitHub API credentials

Quick Setup Guide

  1. Download the JSON template file
  2. Import into your n8n instance
  3. Configure the Google Sheets connection with your translation sheet ID
  4. Set up GitHub credentials with repository access
  5. Map your .strings file locations in the workflow
  6. Test with a small subset of translations first

Pro tip: Schedule this workflow to run automatically before each localization sprint to ensure all translation gaps are identified and assigned before work begins.

Key Benefits

Eliminates manual comparison errors that often occur when checking translation completeness across multiple files and languages. The automated process ensures 100% coverage checking.

Reduces localization cycle time by 60-80% by removing the manual gap identification process that typically takes developers several hours per release.

Improves translator efficiency by providing clear GitHub PRs with exact placeholder locations for missing translations, eliminating back-and-forth communication about what needs translation.

Maintains version control integrity by working through proper GitHub branches and PRs rather than direct file modifications.

Frequently Asked Questions

Common questions about iOS localization automation

The main challenges include keeping translation files synchronized across multiple languages, tracking which strings need translation, and managing updates without overwriting existing translations. Most teams struggle with manual processes that are error-prone and time-consuming.

Automation solves these by automatically detecting new or modified strings, flagging missing translations, and maintaining proper version control. For example, when adding new features, the system can identify exactly which new strings need translation across all target languages.

  • Key challenge: Maintaining translation state visibility
  • Common pain point: Manual comparison errors
  • Solution benefit: Automated gap detection

Automation improves quality by ensuring complete coverage and proper context for translators. The system flags all missing translations with references to the original string, preventing omissions that often occur in manual processes.

By working through GitHub PRs, translators see changes in context with version control history. They can also reference previous translations for consistency. One mobile team reduced translation errors by 45% after implementing similar automation.

  • Provides full context for translators
  • Maintains translation consistency
  • Reduces contextual errors

Yes, the workflow properly handles iOS pluralization rules and stringdict files. It maintains the special formatting required for pluralized strings while identifying missing translations for each plural form.

The system recognizes keys like "items.count" and ensures all required plural forms are accounted for in each language. For languages with different pluralization rules (like Arabic's six forms), it validates the complete set exists.

GitHub PRs provide version control, review capabilities, and integration with existing development workflows. While spreadsheets are convenient for translators, PRs ensure changes go through proper code review and CI pipelines.

This approach also prevents accidental overwrites that can happen with direct spreadsheet access. One team reported eliminating 90% of merge conflicts in localization files after switching to this PR-based approach.

Best practice is to run the workflow whenever new strings are added or modified - typically during feature development sprints. Many teams schedule weekly runs during active development phases.

The frequency depends on your release cycle. Continuous localization teams run it automatically with each commit, while others trigger it before translation sprints. The key is catching gaps early rather than right before release.

While this template uses Google Sheets, the workflow can be adapted for other systems like Crowdin, Lokalise, or Phrase. The core logic of comparing source strings with translations remains the same.

The GitHub PR generation would work similarly regardless of translation system. Many professional translation platforms offer direct GitHub integration, which could replace the Google Sheets component entirely.
