SheetNext demo

SheetNext is a pure front-end, high-performance spreadsheet engine that provides enterprises with a ready-to-use intelligent spreadsheet foundation.
With the AI-driven development approach, a single developer + AI can integrate and deliver complex enterprise spreadsheet solutions.
Common scenarios like ledgers, budgets, analytics, data entry, and approvals can produce a first version in minutes.

✨ Key Features

📊 Full Spreadsheet Capabilities — Formula engine, charts, pivot tables, super tables, slicers, conditional formatting, data validation, sparklines, freeze panes, sorting & filtering, and more
🤖 AI-Powered Workflow — Built-in AI automation for template generation, data analysis, formula writing, and cross-sheet logic
📁 Native File Support — Import/export Excel (.xlsx), CSV, and JSON out of the box, no extra plugins needed
🚀 Zero-Config Setup — All features built in, no additional dependencies required
⚡ High-Performance Rendering — Canvas-based virtual scrolling handles large datasets with ease

🚀 Quick Start

SheetNext can be integrated with just a few lines of code and works with any front-end framework (Vue, React, Angular, etc.).

Option 1: Traditional Integration

Install via npm

npm install sheetnext

<!-- Container for the editor -->
<div id="SNContainer" style="width:100vw;height:100vh;padding:0 7px 7px"></div>

import SheetNext from 'sheetnext';
import 'sheetnext.css';

const SN = new SheetNext(document.querySelector('#SNContainer'));

Browser Direct Import (CDN)

  <script>
    const SN = new SheetNext(document.querySelector('#SNContainer'));
  </script>
</body>
</html>

Internationalization (i18n)

The default language is English (en-US). A built-in Chinese (zh-CN) locale is available.

Import locale via npm:

import SheetNext from 'sheetnext';
import zhCN from 'sheetnext/locales/zh-CN.js';

SheetNext.registerLocale('zh-CN', zhCN);

const SN = new SheetNext(document.querySelector('#SNContainer'), {
  locale: 'zh-CN'
});

Import locale via CDN:

<script src="https://cdn.jsdelivr.net/npm/sheetnext/dist/sheetnext.umd.js"></script>
<script src="https://cdn.jsdelivr.net/npm/sheetnext/dist/sheetnext.locale.zh-CN.umd.js"></script>
<script>
  const SN = new SheetNext(document.querySelector('#SNContainer'), {
    locale: 'zh-CN'
  });
</script>

Option 2: AI-Driven Development (Recommended)

Step 1: Download the AI Development Reference

For Codex Skills, use the ready-to-install skill directory: docs/skill/sheetnext-dev/.
For other AI tools, open docs/skill/sheetnext-dev/references/ in the repository.
The core references are docs/skill/sheetnext-dev/references/core-api.md, docs/skill/sheetnext-dev/references/events.md, and docs/skill/sheetnext-dev/references/enums.md.
Protocol supplements are docs/skill/sheetnext-dev/references/ai-relay.md and docs/skill/sheetnext-dev/references/json-format.md.

Step 2: Use the Skill or Feed `references` to Your AI Tool

For Codex, copy the generated skill into your Codex skills directory, then restart Codex:

Copy-Item -Recurse -Force .\docs\skill\sheetnext-dev "$env:USERPROFILE\.codex\skills\sheetnext-dev"

For Cursor / Claude / ChatGPT / Copilot or any AI coding assistant, provide the docs/skill/sheetnext-dev/references/ reference set first, then describe your requirements.

Recommended prompt template:

You are a senior SheetNext AI development expert. Please read and understand the documentation I provide, then give a directly implementable solution.
Execution order:
1) Read: docs/skill/sheetnext-dev/references/core-api.md
2) Read as needed: docs/skill/sheetnext-dev/references/events.md, docs/skill/sheetnext-dev/references/enums.md, docs/skill/sheetnext-dev/references/ai-relay.md, and docs/skill/sheetnext-dev/references/json-format.md
3) Identify user goals (business goals + technical goals)
4) Output a minimum viable implementation (get it running first, then optimize)
5) All APIs and code must strictly follow the documentation
6) Provide verification steps and risk points
Constraints:
- Do not fabricate APIs
- Do not skip edge cases
- Prioritize reusing existing capabilities, avoid over-engineering

Step 3: Describe Your Business Goal

For example:

"Build a sales pivot analysis template with charts and slicers"
"Build a multi-sheet budget entry system with permissions and printing"
"Migrate an existing Excel template to an online editable version"
