Format Customization

Output formats

Markdown (.md)

Default. One file per day. YAML frontmatter (optional) plus headed sections per category.

Obsidian Bases

Markdown with structured frontmatter optimized for Obsidian's Bases plugin. Numeric properties stay numeric, dates stay dates.

JSON

One JSON file per day. Easy to script against. Top-level fields include date, type, and units, followed by category objects.

CSV

One CSV file per day using Date,Category,Metric,Value,Unit,Timestamp. Daily aggregates leave Timestamp blank; sample rows include an ISO timestamp.

Date & time

Pickers for date format (e.g. YYYY-MM-DD, MMM d, yyyy) and time format (12-hour, 24-hour). The preview block at the bottom of the screen updates live as you change settings.

Unit system

Toggle between Metric and Imperial. Affects distance (m/km vs ft/mi), weight (kg vs lb), temperature (°C vs °F), and a few others. HealthKit always stores in canonical units; conversion happens at export time.

Frontmatter fields

Tapping Frontmatter Fields opens a dedicated editor:

Toggle individual built-in fields (date, weekday, totalSteps, etc.)
Rename a field — useful if your Obsidian setup expects different keys
Add custom fields with static values (e.g. type: health)
Add placeholder fields that resolve at export time (e.g. weather: {weather})

Markdown template

Tapping Markdown Template opens a template editor with several built-in styles (Compact, Sections, Detailed) plus a fully custom mode. The preview block shows the result for today's data.

Preview

At the bottom of the Format screen, a live preview block renders today's data with your current settings. This is the fastest way to iterate — change a toggle, look at the preview, repeat.
