The easiest way to manage translation files for web and mobile apps.

SimpleLocalize CLI is a command-line tool that allows you to manage translations in your software project, and it's a great tool for CI/CD pipelines and localization automation.

• Upload and download translations. The main purpose of the command-line tool is to upload and download translation files from Translation Editor to your project.
• Auto-translate strings. Start auto-translation jobs from the command-line and get translated strings in a few minutes.
• Hosted translations management. Push and pull translations from Translation Hosting to your project using the command-line.
• GitHub Actions support. Use SimpleLocalize CLI in your GitHub Actions workflows.
• Check project status. Get project details from the command-line and check if your translations are up-to-date.

The installation process is automated by command-line scripts. Both scripts for Windows (PowerShell) and macOS/Linux/Windows downloads a binary file with CLI, copies it to user files and makes it available to run anywhere in the system from a command-line.

# macOs / Linux / Windows (WSL)
curl -s https://get.simplelocalize.io/2.7/install | bash

# Windows (PowerShell)
. { iwr -useb https://get.simplelocalize.io/2.7/install-windows } | iex;

To change or update the CLI version, run the installation script with the desired version number in the URL, e.g.:

• https://get.simplelocalize.io/2.0.6/install installs version 2.0.6 on macOS/Linux/Windows (WSL)
• https://get.simplelocalize.io/2.0.6/install-windows installs version 2.0.6 on Windows (PowerShell)

See releases for the list of available versions.

The command-line tool offers several commands to execute. All of them requires Project API Key that is unique for each project. You can set apiKey in simplelocalize.yml configuration file, pass it as parameter with --apiKey or set it by environment variable SIMPLELOCALIZE_API_KEY.

simplelocalize [command] ...parameters

Available commands:

• init - creates a sample configuration file
• status - gets translation project details
• upload - uploads translation files or translation keys
• download - downloads translation files
• auto-translate - starts auto-translation jobs
• pull - downloads translation files from Translation Hosting
• publish - publishes translations to Translation Hosting
• purge - removes all translation, translation keys and languages from the project
• extract - finds and extracts translation keys in your project files

Command creates a sample configuration file in the current directory. The configuration file simplifies the usage of the command-line tool by providing a default configuration for the project and allowing to omit some parameters.

simplelocalize init

Upload command takes your local files and uploads them to SimpleLocalize. You can specify a path to the file or use placeholders to upload many files at once. A good practise is to upload only source translations instead of uploading all translations on each run. You can use {lang} placeholder to specify language or locale and {ns} placeholder to specify namespace, e.g.: ./src/translations/{lang}/{ns}.json.

simplelocalize upload 
  --apiKey <PROJECT_API_KEY>
  --uploadPath <UPLOAD_PATH_PATTERN>
  --uploadFormat <UPLOAD_FORMAT>

Upload format is a format of the file(s) with translations. See available upload formats

Additional parameters:

• --replace allows you to replace existing translations with new ones,
• --dryRun allows you to check what translation files will be uploaded without actually uploading them,
• --namespace download translations for a specific namespace, e.g.: --namespace home,
• --customerId download translations for a specific customer, e.g.: --customerId ikea,
• --uploadOptions allows you to pass additional options to the upload command, E.g.: --options TRIM_LEADING_TRAILING_SPACES. To pass multiple options, use comma as a separator.

Since version 2.7 you can skip 'upload' part in the parameters names, e.g.: --path instead of --uploadPath.

└── locales
    └── messages.json

Command:

simplelocalize upload 
  --apiKey <PROJECT_API_KEY>
  --uploadPath ./locales/messages.json
  --uploadFormat multi-language-json

In this example we upload only source translations from ./en/messages.json and uses --uploadLanguageKey en-GB to specify language key for the uploaded file for the Translation Editor. It's a recommended way to upload source translations.

.
├── ca
│   └── messages.json
├── en
│   └── messages.json
└── es
    └── messages.json

Command:

simplelocalize upload 
  --apiKey <PROJECT_API_KEY>
  --uploadPath ./en/index.json
  --uploadLanguageKey en-GB
  --uploadFormat single-language-json

In this example we use {lang} placeholder to upload many files at once and specify language key for each file. It's not a recommended way to upload source translations, as it uploads more files than necessary.

.
├── ca
│   └── index.json
├── en
│   └── index.json
└── es
    └── index.json

Command:

simplelocalize upload 
  --apiKey <PROJECT_API_KEY>
  --uploadPath /{lang}/index.json
  --uploadFormat single-language-json

In this example we use {ns} placeholder to upload many files at once for the English language. We used --uploadLanguageKey en-GB to specify language key for the uploaded file for the Translation Editor.

.
├── italian
│   ├── common.json
│   └── home.json
├── english
│   ├── common.json
│   └── home.json
└── spanish
    ├── common.json
    └── home.json

Command:

simplelocalize upload 
  --apiKey <PROJECT_API_KEY>
  --uploadPath /english/{ns}.json
  --uploadLanguageKey en-GB
  --uploadFormat single-language-json

Download works similarly to the upload command, but this time it exports translation files from the Translation Editor to your local files.

simplelocalize download 
  --apiKey <PROJECT_API_KEY>
  --downloadPath <DOWNLOAD_PATH_PATTERN>
  --downloadFormat <DOWNLOAD_FORMAT>

Download format is a format of the file(s) with translations. See available upload formats

Same as before you can use {lang} and {ns} placeholders to download many files at once and specify language keys that should be downloaded, eg.:

simplelocalize download 
  --apiKey <PROJECT_API_KEY>
  --downloadPath ./src/{ns}/messages_{lang}.json
  --downloadFormat single-language-json
  --downloadLanguageKey en,de,fr

Additional parameters:

• --downloadLanguageKey allows you to download translation for specified languages. E.g.: --languageKey en,de,fr.
• --downloadCustomerId allows you to download translations for a specific customer. E.g.: --customerId ikea.
• --downloadNamespace allows you to download translations for a specific namespace. E.g.: --namespace home.
• --downloadOptions allows you to pass additional options to the download command. E.g.: --options WRITE_NESTED.
• --downloadSort allows you to sort translations in the downloaded file. E.g.: --sort NEWEST_KEYS_FIRST. Available options: NEWEST_KEYS_FIRST, NEWEST_KEYS_LAST, NAMESPACES, IMPORT_ORDER.

Since version 2.7 you can skip 'download' part in the parameters names, e.g.: --path instead of --downloadPath.

Auto-translate command starts auto-translation tasks for all languages in the project or for languages specified in --languageKeys parameter. Auto-translation configuration is taken from the last auto-translation job in the project for the given language.

simplelocalize auto-translate --apiKey <PROJECT_API_KEY>

Additional parameters:

• --languageKeys allows you to specify project language keys to auto-translate, e.g.: --languageKeys en,de,fr.

It publishes translation to Translation Hosting. It behaves exactly the same as publish buttons in the SimpleLocalize (Hosting tab).

Publishes translations from Translation Editor to the _latest environment.

simplelocalize publish --apiKey <PROJECT_API_KEY> --environment _latest

Publishes translations from the _latest environment to _production environment.

simplelocalize publish --apiKey <PROJECT_API_KEY> --environment _production

Downloads all translation hosting files to given directory in --pullPath parameter. It overwrites existing files and creates subdirectories if necessary.

Pulls translations from the _latest environment.

simplelocalize pull --apiKey <PROJECT_API_KEY> --pullPath ./hosting/ --environment _latest

Pulls translations from the _production environment.

simplelocalize pull --apiKey <PROJECT_API_KEY> --pullPath ./hosting/ --environment _production

If you would like to filter files which should be downloaded you can use --filterRegex param, e.g.: --filterRegex '__index.json' will download only __index.json file.

Command gets project details and prints them to the console.

simplelocalize status --apiKey <PROJECT_API_KEY>

Command removes all translations, translation keys and languages from Translation Editor.

simplelocalize purge --apiKey <PROJECT_API_KEY>

Additional parameters:

• --force allows you to skip confirmation prompt.

Extract command finds translation keys and translations from project source code at <SEARCH_DIRECTORY> and exports them to extraction.json file that uses simplelocalize-json file format.

simplelocalize extract 
  --searchDir <SEARCH_DIRECTOR>
  --projectType <PROJECT_TYPE> 

See available project types.

Use configuration file to simplify your bash command. Arguments used in command always override properties set in the configuration file. By default, SimpleLocalize will load configuration from file named simplelocalize.yml. You can load configuration from different location by using a -c parameters.

# Load default simplelocalize.yml file
simplelocalize upload

# Use configuration file at custom location
simplelocalize -c my-configuration.yml upload

SimpleLocalize CLI supports HTTP and HTTPS proxies, and it respects the http_proxy, https_proxy environment variables.

Here are some examples of how to set proxy environment variables in Linux and macOS:

export http_proxy=http://someproxy.com
export http_proxy=http://someproxy.com:8080
export http_proxy=http://user:password@someproxy.com:8080
