CENTCOM.io Notes Import / Export Format

CENTCOM.io uses a JSON-based format designed for maximum interoperability. This format supports rich content, attachments, tags, and folder organization.

Format Version

Current version: 1.0

Export Options

CENTCOM.io supports two export formats:

1. JSON + ZIP Archive — Recommended for large attachments. Exports a .zip file containing notes.json and an attachments/ folder with original files.
2. Single JSON File — For portability. Attachments are base64-encoded inline (larger file size).

Export Structure (ZIP Archive)

The recommended ZIP export contains:

centcom-export-2026-01-02.zip
├── notes.json
└── attachments/
    ├── 550e8400.../example_filename.pdf
    └── 661f9511.../image.png

JSON Format

The notes.json file structure:

{
  "version": "1.0",
  "exported_at": "2026-01-02T20:50:00Z",
  "app": "centcom.io",
  "export_type": "archive",  // or "inline" for base64
  "account": {
    "email": "user@example.com",
    "name": "John Doe"
  },
  "notes": [
    {
      "uuid": "550e8400-e29b-41d4-a716-446655440000",
      "title": "Meeting Notes",

      "content_html": "<p>Rich HTML version...</p>",
      "created_at": "2026-01-01T10:00:00Z",

        }
      ]
    }
  ]
}

Field Definitions

Field	Type	Description
`version`	string	Format version for compatibility checking
`exported_at`	string (ISO 8601)	UTC timestamp of export
`uuid`	string (UUID v4)	Unique identifier for deduplication on re-import
`title`	string	Note title (may be empty)
`content_text`	string	Plain text version of note content
`content_html`	string	HTML version with formatting preserved
`folder`	string \| null	Folder path (e.g., "Work" or "Work/Projects")
`tags`	array	List of tag strings
`attachments`	array	List of attachment objects (see below)
`attachments[].path`	string	Relative path to file in ZIP archive (archive export)
`attachments[].data`	string	Base64-encoded file content (inline export)

Inline Attachment References

When users drag/drop files onto the note editor, an inline reference marker is inserted into the note content:

// Active attachment reference (green text in editor)
[[[ 📎 ATTACHED: example_filename.pdf ]]]

// Deleted attachment reference (gray text + strikethrough)
// Applied via rich text formatting, not wrapped HTML
[[[ 📎 ATTACHED: example_filename.pdf ]]]  ← with color:#999 + strike formatting

These markers appear in content_html and content_text. The actual file data is stored separately in the attachments array. When importing, you may:

• Parse these markers to identify which attachments are referenced inline
• Preserve them as-is for display compatibility
• Convert them to your app's native attachment format

Import Behavior

When importing notes:

• Notes with matching uuid will be updated (not duplicated)
• Missing folders will be created automatically
• Both content_text and content_html are accepted; HTML takes precedence if both provided
• Attachments with path are read from the ZIP archive
• Attachments with data are decoded from base64
• All attachments are stored as separate files on disk (not inline)
