Custom File Format Module

Use this module to add support of new custom file formats. It’s implemented by delegating a source file parsing to an app with a custom file format module. When translations are completed, Crowdin passes an array with translations to the Custom file format app that generates the translation files. This module is available to project members with manager permissions (or higher).

Custom File Format module structure:

{
  "custom-file-format": [
    {
      "key": "your-module-key-type-xyz",
      "type": "type-xyz",
      "url": "/process",
      "multilingual": true,
      "signaturePatterns": {
        "fileName": "^.+\\.xyz$",
        "fileContent": "<properties>\\s*<property\\s+name=.*value=.*/>"
      }
    }
  ]
}

Properties:

key

Type: string

Required: yes

Description: Module identifier within the Crowdin app.

type

Type: string

Required: yes

Description: The custom file format identifier. Can be used in API to force the processing of the files by the Custom file format app. If the type parameter is used in API, the signaturePatterns will be ignored.

url

Type: string

Required: yes

Description: The relative URL triggered on file import, update, translation upload, and export.

multilingual

Type: bool

Required: no

Allowed values: true, false. Default is false

Description: This parameter is used to combine the content of multiple languages into one request when uploading and downloading translations in your Crowdin project.

signaturePatterns

Type: object

Description: Contains fileName and/or fileContent regular expressions used to detect file type when uploading a new source file via UI (or via API without specified type parameter). If the file matches regular expressions, it's labeled as a custom format file.

Note: fileContent regular expression checks only the first 64 KB of the file content.

Communication between Custom File Format App and Crowdin

On the initial file import, the system detects custom file format using the signaturePatterns or type parameters and makes an HTTP request to the app’s URL ($baseUrl . $url) for further processing. Then app processes the file in a custom format and responds to the system. The requests and responses to and from the custom file format apps have two-minute timeouts. The maximum request and response payload size is limited to 5 MB.

Request to the App

Request payload example:

// max request payload - 5 MB
// wait timeout - 2 minutes
{
    "jobType": "parse-file | build-file",
    "organization": {
        "id": 1,
