DocxSectioner

A utility for modular processing of large academic manuscripts.

Download for macOS (Intel): DocxSectioner_v2_mac_intel.zip

This tool allows you to split a single .docx file into multiple documents based on a chosen Heading Style. Each resulting file is named after the heading text and numbered sequentially.

Important: macOS Security Note

Since this is an independent academic tool, macOS may show a warning that the developer cannot be verified. To open the app for the first time:

  1. Right-click (or Control-click) the DocxSectioner icon.
  2. Select Open from the shortcut menu.
  3. Click Open again in the dialog box that appears.

Why DocxSectioner?

In my own writing experience, I found that most existing tools for splitting Word documents are highly destructive. They often strip away styles, corrupt tables, or lose images, making it impossible to merge the fragments back into a consistent master document later.

DocxSectioner v2 was built specifically to solve this. It performs a "surgical" split, preserving the entire internal XML structure of the original document. This ensures that when you later use DocxMelter to reassemble your chapters, the final dissertation or monograph remains perfectly formatted, with all styles, citations, and images intact.

One of the most critical features for linguists is the preservation of global numbering sequences. If your original manuscript contains hundreds of numbered linguistic examples, DocxSectioner ensures that each split fragment retains its internal numbering references. This prevents the common "reset to 1" error found in other tools.

How it works

  1. Launch the application and select your source .docx file.
  2. The tool will automatically detect all used styles. Choose the heading style you want to use as a separator (e.g., Heading 1 or a custom Chapter Title).
  3. Select an output folder and click Start.

Note on file sizes: You may notice that the individual split files are relatively large. This is intentional. To ensure 100% structural integrity, each part carries over the full metadata, style definitions, and image cache from the source document. This "heavy" approach is what allows for perfect reassembly later.
