Convert YAML to Wiki

Why Convert YAML to Wiki?

Converting YAML to MediaWiki markup enables you to publish structured configuration data, technical specifications, and data catalogs directly to Wikipedia-style wiki platforms. Wiki markup transforms raw YAML key-value pairs into richly formatted pages with headings, tables, lists, and cross-references that are easy for teams to read and collaboratively edit.

This conversion is especially valuable for DevOps teams and technical writers who maintain internal knowledge bases. Configuration data stored in YAML files can be automatically transformed into well-structured wiki pages with formatted tables for key-value pairs, bulleted lists for sequences, and hierarchical headings for nested objects. This bridges the gap between machine-readable configuration and human-friendly documentation.

Our converter maps YAML structures to appropriate MediaWiki elements: top-level keys become headings, nested objects become sub-sections or wikitables, and lists become bulleted items. The resulting wiki markup is ready to paste into any MediaWiki-powered site, from corporate Confluence-like wikis to public Wikipedia pages.

Key Benefits of Converting YAML to Wiki:

• Documentation Ready: Publish YAML configurations as formatted wiki pages
• Formatted Tables: Key-value pairs rendered as clean wikitables
• Hierarchical Headings: Nested YAML objects mapped to section headings
• Collaborative Editing: Wiki pages support versioning and team contributions
• Rich Formatting: Bold keys, bulleted lists, and structured layout
• Cross-Platform: Works on any MediaWiki, Wikipedia, or Fandom site

Practical Examples

Example 1: Project Metadata

Input YAML file (project.yaml):

project:
  name: CloudDeploy
  version: 2.5.0
  license: MIT
  authors:
    - Alice Johnson
    - Bob Smith

Output Wiki file (project.wiki):

== Project ==
{| class="wikitable"
! Key !! Value
|-
| '''name''' || CloudDeploy
|-
| '''version''' || 2.5.0
|-
| '''license''' || MIT
|}

=== Authors ===
* Alice Johnson
* Bob Smith

Example 2: API Endpoint Documentation

Input YAML file (api-endpoints.yaml):

endpoints:
  - path: /api/users
    method: GET
    description: List all users
    auth: required
  - path: /api/users/{id}
    method: DELETE
    description: Delete a user
    auth: admin

Output Wiki file (api-endpoints.wiki):

== Endpoints ==
{| class="wikitable"
! Path !! Method !! Description !! Auth
|-
| /api/users || GET || List all users || required
|-
| /api/users/{id} || DELETE || Delete a user || admin
|}

Example 3: Server Inventory

Input YAML file (inventory.yaml):

datacenter: us-east-1
servers:
  - hostname: web-01
    role: frontend
    os: Ubuntu 22.04
  - hostname: db-01
    role: database
    os: Debian 12

Output Wiki file (inventory.wiki):

'''Datacenter:''' us-east-1

== Servers ==
{| class="wikitable"
! Hostname !! Role !! OS
|-
| web-01 || frontend || Ubuntu 22.04
|-
| db-01 || database || Debian 12
|}

Frequently Asked Questions (FAQ)

Q: What is MediaWiki markup?

A: MediaWiki markup (also called wikitext) is the formatting language used by Wikipedia and all MediaWiki-powered websites. It uses special characters to define headings (== Heading ==), bold text ('''bold'''), links ([[Page]]), lists (* item), and tables ({| class="wikitable" ... |}). The MediaWiki engine renders this markup as formatted HTML pages.

Q: How are YAML nested objects converted to wiki format?

A: Top-level YAML keys become wiki headings (== Heading ==), and nested keys become sub-headings (=== Sub-heading ===). Simple key-value pairs within objects are rendered as wikitables. Lists are converted to bulleted (* item) or numbered (# item) wiki lists, preserving the hierarchical structure.

Q: Can I use the output on Wikipedia?

A: Yes. The output uses standard MediaWiki markup syntax that is fully compatible with Wikipedia, Fandom, Miraheze, and any other MediaWiki-based wiki. You can paste the output directly into the wiki editor.

Q: Are YAML comments preserved in wiki output?

A: YAML comments are not directly preserved as wiki content. However, they can be converted to HTML comments () within the wiki markup, which are hidden from readers but visible in the page source.

Q: How are YAML lists converted?

A: YAML sequences (lists) are converted to MediaWiki bulleted lists using the * prefix. Lists of objects with consistent keys are converted to wikitables with column headers. Nested lists produce indented wiki list items using ** syntax.

Q: What happens if my YAML file has syntax errors?

A: If the YAML file contains syntax errors, the converter will treat the content as plain text and wrap it in a wiki preformatted block. You will still receive a valid .wiki file.

Q: Is there a file size limit for conversion?

A: Our converter handles YAML files of any reasonable size. Complex nested structures with many levels of depth are fully supported, producing well-organized wiki markup with appropriate heading levels.
