Stop Breaking Production Builds with Google Translate

Google Translate was built for prose, not code. StrucTrans parses your JSON at the AST level—translating human text values while locking keys, commas, brackets, and variables with 100% syntax safety.

Google Translate (Broken Syntax)

Syntax Error

"bienvenido_key": "{ Nombre }!" Key translated & variable mangled with spaces

StrucTrans (100% Valid AST)

100% Valid AST

"welcome_key": "¡Bienvenido, {name}!" Key locked & variable {name} preserved 100%

TL;DR Executive Summary

Copy-pasting JSON into Google Translate causes 3 critical errors: translated key identifiers, broken quotes/commas, and mangled variables like {name} or %s. StrucTrans isolates string values from code structure, guaranteeing 100% valid JSON output.

Architectural Advantages

Why Generic Translators Fail Developer Workflows

Four key reasons why structure-aware translation is mandatory for software localization.

1. Key & Syntax Lock (100% AST Protection)

When pasting JSON into Google Translate, property keys like "checkout_button" get translated to "botón_pago", breaking front-end key lookups like t('checkout_button'). StrucTrans locks object keys, ensuring your target locale matches source keys 1-to-1.

2. Variable & Token Preservation

Tokens such as {userName}, %s, or ICU plurals often get translated or corrupted into { Nombre de usuario } by general MT engines. StrucTrans masks variables before translation and re-inserts them into valid semantic positions.

3. Zero Manual Syntax Debugging

Developers waste up to 45 minutes fixing missing quotes, invalid trailing commas, or corrupted brackets after manual copy-pasting. StrucTrans validates JSON formatting automatically prior to file export.

4. Zero Subscription & Setup Overhead

Traditional Translation Management Systems (TMS) charge $100+/month and require setting up complex projects just to translate a single file. StrucTrans provides an instant web UI without paywalls or project setup requirements.

Frequently asked questions

Why does Google Translate break JSON files?

Google Translate treats code as plain natural language. It translates object keys, distorts structural syntax (quotes, commas, brackets), and alters variable placeholders like {name} or %s into translated words.

How does StrucTrans prevent JSON syntax errors during translation?

StrucTrans uses an AST-level structure-aware parser that isolates key names, syntax tokens, and ICU/sprintf variables. Only string values are sent for translation while structural code remains locked.

Does StrucTrans support nested JSON structures and arrays?

Yes. StrucTrans recursively traverses complex nested JSON objects and arrays of string items while leaving key names and hierarchy intact.

Is StrucTrans free to use for developers?

Yes. StrucTrans offers a free online web interface for instant i18n file translation without mandatory account registration or subscription setups.
