Localization QA

Find missing keys, placeholder defects, whitespace changes and access-key issues in supplied translation dictionaries. No model required.

Run and download

1. Keep the included sample or replace Input data with your own authorized records.
2. Start a run. Open Report and CSV downloads when it finishes.
3. Open OUTPUT for the complete JSON report and download the CSV records.
4. Review the findings before importing or publishing changes. This Actor never writes to a store.

Hosted limits

5 target languages and 500 keys per dictionary; 1 MiB JSON input. Flat JSON dictionaries only. These tighter hosted limits take precedence over the core format limits below. Memory is fixed at 256 MB. Default timeout is 60 seconds. Output includes one dataset summary row; individual findings and records are delivered in OUTPUT and CSV files. No model subscription, external API key or other product purchase is required.

Price

$0.05 per run, charged once when the Actor starts. All report and CSV output is included, with no per-row fee or platform-usage surcharge. Set the maximum run cost to at least $0.05. Starts that reject invalid input or produce no findings still incur the start charge; validate the input before running.

Storage and support

Apify stores supplied data and generated reports under its storage access/retention settings. This hosted edition sends input to Apify; it is not the local-only edition. Remove sensitive run data when no longer needed. URLs in input are never fetched. Use the Actor issue tracker for support with a non-sensitive example and run ID. Do not post private exports or credentials. Hosted use does not grant source redistribution rights.

Input and interpretation

See examples/input.json. Source maps arbitrary resource IDs to source strings. Translations maps language labels to dictionaries with those same IDs. English-as-key input works by supplying the same English text as each source key and value. Nested objects and arrays are rejected; flatten them before input. Limits: 5 MiB, 50 target languages, 10000 keys per dictionary, 500-character keys and 20000-character values.

Choose an explicit placeholder mode: numbered for {0}, named for {name}, or none for literal text without placeholder validation. Reordering is allowed, but names and occurrence counts must match. Double braces are literal escapes in named and numbered modes. ICU plurals/select expressions, .NET format specifiers, printf and template-language expressions are not supported and must not be treated as validated by this tool. Unsupported brace syntax produces a finding.

Set accessKeys true for underscore accelerators, false for ordinary underscores. Two consecutive underscores represent one literal underscore and no accelerator. Leading/trailing whitespace must match exactly. Missing, empty, malformed and structurally different strings are errors. Extra keys and unchanged source strings are warnings requiring human review, since names and technical terms can legitimately remain unchanged. JSON preserves exact values; CSV guards formula-like cell prefixes.

This tool does not generate or certify translations, check UI layout, or grant release approval. A structural pass can still contain warnings and incorrect translations.
