Convert YAML to FB2

Why Convert YAML to FB2?

Converting YAML to FB2 format is valuable when you need to create e-books readable on devices and applications popular in the Russian-speaking world. FB2 is the dominant e-book format in Russia and CIS countries, supported natively by popular e-readers like PocketBook and ONYX BOOX, and by reading apps such as FBReader, CoolReader, and AlReader.

This conversion is particularly useful for teams that document their infrastructure or API configurations in YAML and need to distribute this documentation to Russian-speaking teams or clients who prefer the FB2 format. The resulting e-book includes proper section structure, metadata, and is ready for import into any FB2-compatible library manager.

Our converter maps YAML structures to FB2 XML elements: top-level keys become titled sections, nested objects create sub-sections, lists become formatted paragraphs, and the complete book metadata (title, description) is populated from the YAML content. The output is a valid FB2 XML file that passes validation against the FictionBook schema.

Key Benefits of Converting YAML to FB2:

• CIS Region Compatibility: FB2 is the standard e-book format in Russia and neighboring countries
• Self-Contained: Everything (text, metadata, images) stored in a single XML file
• Rich Metadata: Automatic generation of book title, description, and structure
• Library Integration: Easy import into Calibre, FBReader, and digital library systems
• Compact Size: Text-based FB2 files are very small; can be further compressed as .fb2.zip
• E-Reader Ready: Native support on PocketBook, ONYX BOOX, and similar devices
• XML Parseable: Standard XML format that can be processed by any XML tool

Practical Examples

Example 1: Server Configuration Documentation

Input YAML file (server-config.yaml):

server:
  hostname: prod-web-01
  ip: 192.168.1.100
  os: Ubuntu 22.04
  services:
    - nginx
    - postgresql
    - redis
  firewall:
    ssh: 22
    http: 80
    https: 443

Output FB2 XML structure:

<section>
  <title><p>Server</p></title>
  <p>Hostname: prod-web-01</p>
  <p>IP: 192.168.1.100</p>
  <p>OS: Ubuntu 22.04</p>
  <section>
    <title><p>Services</p></title>
    <p>- nginx</p>
    <p>- postgresql</p>
    <p>- redis</p>
  </section>
  <section>
    <title><p>Firewall</p></title>
    <p>SSH: 22</p>
    <p>HTTP: 80</p>
    <p>HTTPS: 443</p>
  </section>
</section>

Example 2: Product Catalog

Input YAML file (products.yaml):

catalog:
  name: Electronics Store
  categories:
    - name: Laptops
      items:
        - model: ThinkPad X1
          price: 1299
        - model: MacBook Air
          price: 999
    - name: Phones
      items:
        - model: Pixel 8
          price: 699

Output FB2 renders as readable e-book:

Electronics Store
=================

Laptops
-------
  ThinkPad X1 - $1299
  MacBook Air - $999

Phones
------
  Pixel 8 - $699

Example 3: Team Structure

Input YAML file (team.yaml):

organization: DevOps Team
lead: Anna Petrova
members:
  - name: Ivan Sidorov
    role: Senior Engineer
    skills:
      - Kubernetes
      - Terraform
  - name: Maria Kozlova
    role: Junior Engineer
    skills:
      - Docker
      - Ansible

Output FB2 renders as readable e-book:

DevOps Team
===========
Lead: Anna Petrova

Members
-------
Ivan Sidorov - Senior Engineer
  Skills: Kubernetes, Terraform

Maria Kozlova - Junior Engineer
  Skills: Docker, Ansible

Frequently Asked Questions (FAQ)

Q: What is FB2 format?

A: FB2 (FictionBook 2.0) is an XML-based e-book format created in Russia by Dmitry Gribov. It stores book content, structure, metadata (author, genre, description), and even embedded images in a single XML file. FB2 is the most popular e-book format in Russia and CIS countries, supported by PocketBook, ONYX BOOX, FBReader, CoolReader, and many other applications.

Q: Where can I read FB2 files?

A: FB2 files can be read on PocketBook and ONYX BOOX e-readers natively, on Android using FBReader, Moon+ Reader, or AlReader, on iOS using FBReader or KyBook, and on desktop using Calibre, FBReader, or CoolReader. You can also convert FB2 to EPUB or MOBI using Calibre for broader compatibility.

Q: Is FB2 an open format?

A: Yes. FB2 is an open XML-based format with a publicly available schema. Anyone can create, read, or convert FB2 files without licensing fees. The format's XML nature makes it easy to parse and transform using standard XML tools and libraries.

Q: How does the converter handle YAML metadata?

A: The converter extracts relevant information from the YAML structure to populate the FB2 metadata fields. The document title is derived from the filename or top-level title key, and the description section is generated from the overall YAML content. This metadata helps with library cataloging and organization.

Q: Can I convert FB2 to other formats afterward?

A: Yes. FB2 is well-supported by Calibre, the popular e-book management tool, which can convert FB2 to EPUB, MOBI, AZW3, PDF, and many other formats. This makes FB2 a versatile intermediate format for reaching multiple e-reader platforms.

Q: What is the difference between .fb2 and .fb2.zip?

A: A .fb2 file is the raw XML document, while .fb2.zip is the same file compressed in a ZIP archive for smaller file size. Most FB2 readers support both formats. Our converter produces the standard .fb2 XML file, which you can optionally compress yourself.

Q: Does FB2 support images from YAML data?

A: FB2 supports images encoded as base64 within the XML file. However, since YAML configuration files typically do not contain image data, the converted FB2 will primarily contain text content organized into sections. If your YAML references image paths, they will be included as text references in the output.
