Syncfusion UWP Spreadsheet Editor

Overview

Build Excel-like spreadsheet applications in UWP using Syncfusion SfSpreadsheet control with full support for workbook operations, formulas, charts, data validation, and ribbon customization.

Key Capabilities

Workbook Operations: Create/open/save Excel files (XLS, XLSX, XLSM, CSV), multiple worksheets, freeze panes, zoom, protection
Cell Operations: Editing, formatting (fonts, colors, borders, alignment), merge cells, comments, hyperlinks, bookmarks
Data Features: 400+ Excel-compatible formulas, named ranges, data validation, conditional formatting, fill series
Advanced Features: Charts, sparklines, clipboard operations, undo/redo, grouping/outlines

Quick Start Examples

Example 1

User: "Show me how to create a spreadsheet with data and formulas"

Result: C# code generated to create workbook, set cell values, and add formulas

Example 2

User: "Add data validation and rules in the spreadsheet control"

Result: C# code generated for spreadsheet control validation and custom rules

Generate UWP Code — Workflow

Trigger keywords: "how to", "add spreadsheet", "code sample", "show me", "example", "snippet", "integrate", "component", "create sample", "code", "sample code", "generate code", "implement", "add to project", "configure spreadsheet"

Step 1: Ask User for Delivery Option

Before showing code, ask:

"How would you like me to provide the solution?

Option 1: Create a new file in skill folder (.codestudio/skills/syncfusion-uwp-spreadsheet-editor/output/)
Option 2: Add code to an existing file in your project (you provide the file path)
Option 3: Just show the code (no files created/modified)

Please select Option 1, 2, or 3."

⏸️ WAIT for explicit user selection before proceeding.

Step 2: Generate Code from Reference Files

Read relevant
```
references/*.md
```
file(s) for requested feature
Build C# and/or XAML code using ONLY snippets from reference files
Do NOT show code yet, do NOT create files yet

Step 3: Handle User Selection

Option 1: Show code → automatically save to

.codestudio/skills/syncfusion-uwp-spreadsheet-editor/output/

(skill folder only) Option 2: Ask for file path → show code → wait for explicit YES confirmation → apply code → ask to build Option 3: Show code with summary and required assemblies → done (no files created/modified)

For Option 2 only: Before generating code, check if the project has the prerequisites from
```
references/gettingstarted.md
```
(Prerequisites and Setup Requirements section). If missing, ask user consent and add them.

Out-of-Scope Requests

When a user asks a question that does NOT match the skill domain (i.e., not related to UWP Spreadsheet, Excel processing, or Syncfusion spreadsheet control), respond with:

"Unable to process the input. Please provide the input in a different way."

Do NOT attempt to:

Generate code outside the spreadsheet/Excel domain
Provide general UWP guidance unrelated to spreadsheet functionality
Process requests for other Syncfusion controls or unrelated frameworks
Assist with non-spreadsheet features

ONLY activate this skill and its workflows when the user's request matches trigger keywords: "spreadsheet", "Excel", "UI", "code", "Ribbon", "UWP" (in context of spreadsheet/Excel).

Code References

All templates and feature snippets live in

references/*.md

. Each file is a focused snippet the agent combines when generating samples.

Flow: Always start with

references/gettingstarted.md

(Prerequisites and Setup Requirements section), then merge matched feature snippets. If no feature keywords match, return only the basic sample.

Rules

Use Only Reference Snippets
- Generate code exclusively from the Markdown files under
```
references/
```
- Do not invent/guess/include any properties, events, API methods, component names, or parameters not present in
```
references/*.md
```
NO FILE MODIFICATIONS WITHOUT PERMISSION
- Never create or modify files/folders in user workspace without explicit user selection and confirmation.
- Cannot create StackPanel, buttons, textblocks, dialogs, MessageBox or any UI elements beyond the Spreadsheet without user permission.
Unsupported Feature Handling
- If the user requests a feature with no corresponding snippet in
```
references/*.md
```
  , respond with:
```
That feature is not currently supported by the Syncfusion UWP Spreadsheet component.
```
- Suggest the closest supported features only if they have snippets
- Explicitly list unsupported items and do not synthesize code for them
Validation Before Write
- Re-validate before writing that all code blocks originate from
```
references/*.md
```
  files
- If validation fails, stop and inform the user
