+## Epic 7 — macOS App (Swift/SwiftUI)
+**Goal:** A beautiful, native macOS app that feels like it belongs on the platform.
+
+### Story 7.13: Export
+
+As a **macOS user**,
+I want to export my CalcPad sheets in multiple formats,
+So that I can share my calculations with others or archive them in a standard format.
+
+**Acceptance Criteria:**
+
+**Given** a sheet is open with calculations and results
+**When** the user selects File > Export > PDF
+**Then** a PDF is generated showing the two-column layout (expressions on the left, results on the right)
+**And** the file is saved to the user-selected location
+
+**Given** a sheet is open
+**When** the user selects File > Export > HTML
+**Then** an HTML file is generated with a styled two-column layout that looks good in any browser
+
+**Given** a sheet is open
+**When** the user selects File > Export > Markdown
+**Then** a Markdown file is generated with expressions and results formatted in a readable way (e.g., a table or code block)
+
+**Given** a sheet is open
+**When** the user selects File > Export > Plain Text
+**Then** a `.txt` file is generated with expressions and results in a simple aligned format
+
+**Given** a sheet is open
+**When** the user selects File > Export > JSON
+**Then** a JSON file is generated with structured data including each line's expression, result, and metadata
+
+**Given** a sheet is open
+**When** the user selects File > Export > CSV
+**Then** a CSV file is generated with columns for line number, expression, and result
+
+**Given** an export format is selected
+**When** the user uses the macOS Share Sheet instead of File > Export
+**Then** the same export functionality is available through the share interface
