Convert DOCBOOK to XLSX

Why Convert DocBook to XLSX?

Converting DocBook to XLSX enables you to extract tabular data from structured technical documentation into a format that supports formulas, charts, sorting, and filtering. DocBook documents often contain data tables, specifications, metrics, and reference data that are more useful in a spreadsheet where users can analyze, manipulate, and visualize the information interactively.

XLSX (Office Open XML Spreadsheet) is the default format for Microsoft Excel and the world's most widely used spreadsheet format. It supports multiple worksheets, complex formulas, charts, conditional formatting, and data validation. By converting DocBook to XLSX, you transform static documentation into a dynamic, interactive data environment.

The conversion process identifies all tables in the DocBook source and creates corresponding worksheets in the XLSX output. Each table becomes a separate worksheet named after its title. Header rows receive bold formatting, and data cells are typed appropriately (numbers as numbers, dates as dates, text as text). Multiple tables in a single document produce a multi-sheet workbook.

This conversion is particularly useful for project managers who need to analyze data from technical documentation, business analysts who want to create reports from documented specifications, and engineers who need to compare data across different versions of documentation. The spreadsheet format enables sorting, filtering, and formulas that are impossible in DocBook's XML format.

Key Benefits of Converting DocBook to XLSX:

• Data Analysis: Sort, filter, and analyze extracted data with formulas
• Multi-Sheet Workbooks: Each DocBook table becomes a separate worksheet
• Data Visualization: Create charts and graphs from documentation data
• Universal Access: XLSX opens in Excel, Google Sheets, and LibreOffice
• Type Detection: Numbers, dates, and text are automatically typed
• Formatted Headers: Table headers receive bold styling automatically
• Stakeholder Friendly: Non-technical users can work with familiar Excel

Practical Examples

Example 1: Server Inventory Report

Input DocBook file (inventory.xml):

<table xmlns="http://docbook.org/ns/docbook">
  <title>Production Servers</title>
  <tgroup cols="4">
    <thead><row>
      <entry>Hostname</entry><entry>IP</entry>
      <entry>CPU Cores</entry><entry>RAM (GB)</entry>
    </row></thead>
    <tbody>
      <row><entry>web-01</entry><entry>10.0.1.10</entry>
        <entry>8</entry><entry>32</entry></row>
      <row><entry>db-01</entry><entry>10.0.1.20</entry>
        <entry>16</entry><entry>128</entry></row>

        <entry>4</entry><entry>64</entry></row>
    </tbody>
  </tgroup>
</table>

Output XLSX file (inventory.xlsx) - Sheet "Production Servers":

| Hostname  | IP         | CPU Cores | RAM (GB) |
|-----------|------------|-----------|----------|
| web-01    | 10.0.1.10  | 8         | 32       |
| db-01     | 10.0.1.20  | 16        | 128      |
| cache-01  | 10.0.1.30  | 4         | 64       |

(Header row: bold, auto-filtered)
(Numeric columns: right-aligned)

Example 2: API Endpoints Reference

Input DocBook file (api-endpoints.dbk):

<table xmlns="http://docbook.org/ns/docbook">
  <title>REST API Endpoints</title>
  <tgroup cols="4">
    <thead><row>
      <entry>Method</entry><entry>Path</entry>
      <entry>Auth</entry><entry>Description</entry>

      <row><entry>POST</entry><entry>/api/users</entry>
        <entry>Yes</entry><entry>Create user</entry></row>
      <row><entry>DELETE</entry><entry>/api/users/:id</entry>
        <entry>Admin</entry><entry>Delete user</entry></row>
    </tbody>
  </tgroup>
</table>

Output XLSX file (api-endpoints.xlsx) - Sheet "REST API Endpoints":

| Method | Path            | Auth  | Description  |
|--------|-----------------|-------|--------------|
| GET    | /api/users      | Yes   | List users   |
| POST   | /api/users      | Yes   | Create user  |
| DELETE | /api/users/:id  | Admin | Delete user  |

(Filterable columns for quick lookup)

Example 3: Multi-Table Document

Input DocBook file (report.xml) with two tables:

<article xmlns="http://docbook.org/ns/docbook">
  <title>Quarterly Report</title>
  <table>
    <title>Sales by Region</title>
    <tgroup cols="2">
      <thead><row>
        <entry>Region</entry><entry>Revenue</entry>
      </row></thead>
      <tbody>
        <row><entry>North</entry><entry>$125,000</entry></row>
        <row><entry>South</entry><entry>$98,000</entry></row>
      </tbody>
    </tgroup>
  </table>
  <table>
    <title>Sales by Product</title>

Frequently Asked Questions (FAQ)

Q: What is XLSX format?

A: XLSX is the default spreadsheet format for Microsoft Excel since 2007. It is based on the Office Open XML (OOXML) standard (ECMA-376 / ISO 29500). Internally, XLSX files are ZIP archives containing XML files for worksheets, styles, shared strings, and metadata. XLSX supports up to 1,048,576 rows and 16,384 columns per worksheet.

Q: How are multiple DocBook tables handled?

A: Each DocBook table in the document becomes a separate worksheet in the XLSX workbook. The table title (<title>) is used as the worksheet name. If a document contains three tables, the output XLSX file will have three worksheets. Tables without titles are named "Sheet 1", "Sheet 2", etc.

Q: Are numeric values properly typed in Excel?

A: Yes, the converter detects data types and formats cells appropriately. Pure numeric values are stored as Excel numbers (enabling formulas and calculations). Currency values are formatted with currency symbols. Date strings are converted to Excel date values. Text that looks like numbers but should remain text (like phone numbers or ZIP codes) is stored as text.

Q: What happens to non-table content?

A: Non-tabular content (paragraphs, lists, code blocks) can optionally be included in a separate "Content" worksheet as flowing text in column A. Section headings appear in bold cells. Lists are rendered as indented rows. By default, the converter focuses on extracting tabular data, but full document content can be preserved in the spreadsheet if requested.

Q: Can I open the XLSX file in Google Sheets?

A: Yes, Google Sheets fully supports XLSX files. You can upload the converted file to Google Drive and open it directly in Google Sheets. All formatting, multiple worksheets, and data types are preserved. You can also use LibreOffice Calc, Apple Numbers, and other spreadsheet applications that support the XLSX format.

Q: Are header rows formatted?

A: Yes, header rows extracted from DocBook's <thead> elements receive bold formatting, a background color, and auto-filter enabled. This makes it easy to sort and filter data immediately after opening the file. The header row is also frozen (pinned) so it remains visible when scrolling through large datasets.

Q: Can I use formulas in the converted spreadsheet?

A: The converted spreadsheet contains static data extracted from DocBook tables. You can add your own formulas after opening the file in Excel or Google Sheets. Common additions include SUM totals at the bottom of numeric columns, AVERAGE calculations, COUNT functions, and conditional formatting rules for data analysis.

Q: Can I convert XLSX back to DocBook?

A: Yes, our converter supports XLSX to DocBook conversion. The reverse process reads each worksheet and generates DocBook tables with proper <tgroup>, <thead>, and <tbody> structure. Worksheet names become table titles. This round-trip capability is useful for incorporating spreadsheet data into DocBook documentation.
