Frontmatter Cleaner

Quickly review and remove frontmatter (YAML) properties from the note you're currently viewing — without opening the YAML block and editing it by hand.

Why

Notes accumulate stray frontmatter properties over time: leftovers from templates, one-off experiments, or fields you no longer use. Frontmatter Cleaner gives you a single tap-friendly list of the current note's properties so you can pick the ones to remove and delete them in one action.

Usage

1. Open the note you want to clean up.
2. Run Clean frontmatter properties of current file from the command palette, or click the list-checks icon in the ribbon.
3. A modal lists every property in that note's frontmatter, with its current value shown alongside it.
4. Tap or click anywhere on a row — not just the checkbox — to select it for deletion. Selected rows are highlighted.
5. Use the toolbar above the list to select faster: Select all, Select none, or Empty (n) — which catches blank strings, null, and empty lists/objects. The Empty button is disabled when there's nothing of that kind to select.
6. Select Delete selected (n) to remove those properties from the note's frontmatter, or Cancel to close without changes.

Selection and deletion work the same way on desktop and mobile; rows use a 44px minimum touch target so they're easy to tap accurately on iPhone.

Notes

• Deleting properties uses Obsidian's own processFrontMatter API, so the rest of the frontmatter block keeps its existing formatting and order.
• If a note has no frontmatter, the modal tells you instead of showing an empty list.
