Title Serial Number

Obsidian Title Serial Number Plugin

A powerful Obsidian plugin that automatically adds customizable serial numbers to your markdown headings.

Features

• Multiple Number Styles: Support for 7 different numbering styles

  • Arabic numerals (1, 2, 3...)
  • Chinese lowercase (一, 二, 三...)
  • Chinese uppercase (壹, 贰, 叁...)
  • Roman uppercase (I, II, III...)
  • Roman lowercase (i, ii, iii...)
  • Alphabetic uppercase (A, B, C...)
  • Alphabetic lowercase (a, b, c...)

• Flexible Level Configuration: Choose which heading levels (H1-H6) to apply numbering

• Per-Level Style Customization: Set different number styles for each heading level

• Custom Separator: Configure the separator between numbers (e.g., ., -, /)

• Live Preview: See how your serial numbers will look in real-time while configuring

Commands

Numbering that contains alphabetic or Roman numerals uses parentheses, such as (A), (I), or (I.1.a). Arabic and Chinese numbering keep their existing format. The parentheses distinguish these serial numbers from heading text such as A guide or I think, so adding or clearing numbers preserves those words.

Existing notes: Unmarked alphabetic or Roman prefixes from earlier versions are now treated as title text. To update or clear an old serial, first wrap the whole serial in parentheses (for example, # I Introduction becomes # (I) Introduction). Otherwise, adding numbers will retain the old prefix as part of the title. Only mark prefixes that you know are serial numbers.

Configuration

Access the plugin settings through Settings → Community Plugins → Title Serial Number Plugin.
