Why Sheetifye?

Most Flutter apps that deal with data eventually hit the same wall: you need to show a spreadsheet, but the options are either too heavy, require a server, or look nothing like a real Excel file.

Sheetifye solves this with a purpose-built virtualized renderer that parses .xlsx natively, in-app, with no external dependencies. It handles workbooks at any scale while feeling completely native on every platform.

✦ No Excel required     ✦ Works fully offline     ✦ One widget, all platforms

Quick Start

1 · Add the dependency

# pubspec.yaml
dependencies:
  sheetifye: ^1.0.0

flutter pub add sheetifye

2 · Wrap with ProviderScope

Sheetifye uses Riverpod internally. Add ProviderScope at your app root:

void main() {
  runApp(const ProviderScope(child: MyApp()));
}

3 · Drop in the widget

import 'package:sheetifye/sheetifye.dart';

class SpreadsheetPage extends StatelessWidget {
  const SpreadsheetPage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Sheetifye.asset('assets/reports/annual_sales.xlsx'),
    );
  }
}

That's it. You have a fully interactive spreadsheet viewer.

Data Sources

// 📁 From app assets
Sheetifye.asset('assets/data.xlsx')

// 🌐 From a remote URL
Sheetifye.network('https://example.com/reports/q4.xlsx')

// 💾 From the device file system
Sheetifye.file(File('/path/to/spreadsheet.xlsx'))

// 🧠 From raw bytes
Sheetifye.memory(bytes)

---

Theming

Sheetifye.asset(
  'assets/data.xlsx',
  theme: SheetifyeThemeData(
    primary: Colors.indigo,
    accent: Colors.amber,
    headerBackground: Colors.grey.shade100,
    fontFamily: 'Inter',
  ),
)

When no theme is set, Sheetifye inherits your app's active ThemeData and ColorScheme automatically.
