Heading styles

Heading styles are the specific Word styles used to label the sections of a document in a ranked hierarchy: Heading 1 for top-level sections, Heading 2 for subsections, Heading 3 for sub-subsections, and downward. They control the visual look of each heading level (font, size, weight, color, and spacing above and below), but their more important job is structural — Word reads these styles to build an automatic table of contents, populate the Navigation pane for quick jumping, enable collapsible sections, and expose document outline to screen readers for accessibility. A common mistake is faking headings by manually enlarging and bolding text; that looks similar but carries no structure, so tables of contents and navigation break. Proper heading styles also keep every section title in a report or thesis visually identical. Veermat identifies which lines are actually headings and assigns the correct heading style and level consistently throughout the .docx, so structure and appearance match while the file stays editable.
