Free online PLIST to YAML converter

Source format: plist

PLIST stands for property list, a structured data format used primarily in Apple ecosystems. It is common in macOS, iOS, and related development tools for storing application preferences, configuration data, metadata, and small structured records. A plist file can be stored as XML, binary, or occasionally as a simple text-style property list. Developers and system administrators often encounter plist files in app bundles, preference files, launch agents, and build settings.

Target format: yaml

YAML is a human-readable data serialization format widely used for configuration files, deployment manifests, and structured data exchange. It is popular in DevOps, application configuration, and tooling because it is compact, readable, and supports nested structures naturally. Compared with plist, YAML is often easier to edit by hand and is supported by many modern tools and frameworks.

How to perform the conversion

The best conversion method depends on whether your plist is XML or binary. For most cases, the most reliable approach is to use a scripting tool such as Python with a plist parser and a YAML serializer. If you only need a quick conversion, you can also use the built-in converter on 101convert.com for free, without installing any software.

1. Check the plist type. If the file is already XML, it is easier to parse directly. If it is binary, use a tool that can read binary plists.
2. Use a conversion script or utility. Python is a practical choice because it can read plist data and write YAML cleanly.
3. Convert the file. For example, with Python you can load the plist and dump it as YAML using a small script.
4. Verify the output. Open the resulting YAML file in a text editor and confirm that indentation and nested values look correct.

Example workflow with Python:

python convert_plist_to_yaml.py input.plist output.yaml

A typical script would read the plist with plistlib and write YAML using a library such as PyYAML. If you prefer desktop software, you can also inspect plist contents in Xcode or Property List Editor-style tools before exporting or copying the data into YAML manually.

Notes on quality, compatibility, or limitations

Binary plist files must be decoded before conversion; not every text editor can open them correctly. Some plist features do not map perfectly to YAML, especially when the plist contains Apple-specific data types such as NSData, NSDate, or deeply nested arrays and dictionaries that need careful representation. YAML also has its own syntax rules, so indentation errors can make the output invalid. If the plist contains only simple dictionaries, arrays, strings, numbers, and booleans, the conversion is usually straightforward and lossless. For complex or Apple-specific values, check the output carefully after conversion.
