A Career Card file contains structured data representing a professional profile or career card. The contents are organized as JSON objects, arrays, strings, numbers, Boolean values, and null values according to the Career Card specification. The file is intended to be readable by both people and software.
The format uses UTF-8 character encoding, allowing profile data to include international names, descriptions, and other Unicode text. Its registered media type is application/vnd.careercard+json, which helps web services and other applications identify Career Card data when it is transmitted or downloaded.
Career Card is designed for data exchange rather than page layout or document printing. Applications can parse the JSON and render the information as a profile, import it into a career-management system, or process selected fields programmatically. Files should remain valid JSON and follow the required structure defined by the official specification.
The format can be used across operating systems because it is plain text and platform-independent. Compatible software includes Career Card web applications, JSON-aware editors, development tools, and general-purpose programming libraries for JavaScript, Python, Java, and other languages. The specification is available at https://careercard.web.app.
To open a Career Card file for viewing, use a text editor or JSON-aware application. On Windows, Notepad, Notepad++, or Visual Studio Code can display the contents. On macOS, use TextEdit in plain-text mode or Visual Studio Code. On Linux, suitable choices include gedit, Kate, and Visual Studio Code.
For a formatted view, open the file with a browser-based JSON viewer or load it into a Career Card-compatible web application. If the file does not open correctly, verify that it contains valid UTF-8 JSON, that the filename has not been changed incorrectly, and that the application supports the Career Card schema. Avoid editing it with a word processor, which may add formatting that makes the JSON invalid.
Because Career Card is structured JSON, it can be converted to or from other data formats with a JSON parser, script, or data-conversion utility. A compatible application can export profile data as Career Card JSON, while developers can transform it to formats such as CSV, XML, or ordinary JSON after mapping the fields required by the specification. Renaming the file does not convert its contents.
Online JSON converters may be suitable for non-sensitive sample data, but career profiles can contain personal information, so privacy should be reviewed before uploading files. For confidential data, use a desktop tool such as Visual Studio Code, Python, or a Career Card-compatible application and validate the result against the official specification before sharing it.
