ShowInstalledFonts: Quickly List All Fonts on Windows and macOS

Automate Font Inventory with ShowInstalledFonts (PowerShell & Scripts)

Overview

ShowInstalledFonts is a utility/approach for enumerating fonts installed on a system. Automating a font inventory with it (or similar commands/scripts) lets you regularly collect font names, file paths, versions, and metadata for audits, design asset management, or deployment checks.

Goals

• Produce a consistent, machine-readable list of installed fonts.
• Include font name, file path, style/weight, and file metadata (version, date).
• Export to CSV/JSON for reporting or integration with asset systems.
• Run on demand or schedule (Task Scheduler / cron) and optionally centralize results.

Windows — PowerShell approach (example)

Use PowerShell to read installed fonts from the Fonts folder and registry, then export CSV/JSON.

Example script (PowerShell):
