Handsontable is a JavaScript data grid that provides a spreadsheet-like interface for managing and editing large datasets within web applications. It functions as a virtualized data table that renders only visible cells to maintain performance, paired with a synchronization layer that binds the grid to underlying data structures. The project distinguishes itself through a built-in spreadsheet calculation engine for evaluating mathematical and logical expressions and a dedicated tool for exporting grid content into Excel XLSX files. It ensures interoperability with external spreadsheet softwar

Teable is a self-hosted relational data management tool and no-code PostgreSQL database. It provides a spreadsheet-like interface for managing and querying structured data, allowing users to interact with a professional database backend without writing manual SQL for every operation. The platform is an extensible low-code system that allows for the integration of custom plugins and extensions through a dedicated application bridge and marketplace. It enables the creation of tailored internal tools by adding new features or modifying behavior via these external extensions. The system covers a

Gridstudio is a web-based data science integrated development environment that combines a programmatic spreadsheet interface with an interactive Python environment. It functions as a system for organizing and deploying isolated data workspaces to handle data science tasks and storage. The platform merges spreadsheet data management with an execution engine for formulas and Python code, allowing for programmatic spreadsheet manipulation. It enables users to run interactive scripts and terminal sessions to clean, transform, and manage datasets within a browser. The environment supports Linux s

react-data-grid is a high-performance table component for React designed to render large datasets using virtualization. It functions as a virtualizing data table that optimizes memory and performance by rendering only the rows and columns currently visible on the screen. The project provides a customizable spreadsheet interface featuring cell editing, column resizing, and pinned rows. It also acts as a hierarchical data grid, supporting row grouping and tree structures to organize complex nested information. The grid covers wide-ranging data management and display capabilities, including mul

Tabulator is an interactive data table library and virtual DOM data grid used to create high-performance tables from JSON or arrays. It functions as a hierarchical data viewer and a spreadsheet interface component, capable of rendering thousands of records efficiently through viewport-based virtualization and progressive loading. The library distinguishes itself by providing a full spreadsheet interface mode with multi-sheet management, cell range selection, and bulk copy-paste capabilities. It supports complex data architectures, including nested data field mapping, expandable tree structure

react-datasheet ist eine React-Datengitter-Komponente und ein tabellarischer Editor, der eine interaktive Tabellenkalkulations-Schnittstelle bietet. Er ist für die Verwaltung tabellarischer Daten mit integrierter Unterstützung für Zellbearbeitung und Tastaturnavigation konzipiert. Das Projekt zeichnet sich durch seine Flexibilität in Rendering und Struktur aus, was den Austausch von Standard-Tabellenelementen durch benutzerdefiniertes Markup wie Listen oder Divs ermöglicht. Es unterstützt benutzerdefiniertes Zell-Rendering durch ein Mapping-System, das Standardzellen basierend auf Zellmetadaten durch spezialisierte Komponenten ersetzt. Die Komponente deckt breite Funktionen für das Management tabellarischer Daten ab, einschließlich Zustandsverfolgung für Bearbeitungen, Bereichslöschungen und das Einfügen von Daten. Sie bietet zudem Steuerelemente für das Zellverhalten, wie z. B. die Definition des Read-Only-Status und das Spanning von Spalten.

IronCalc is an XLSX spreadsheet engine and formula evaluator designed to compute numerical expressions and manage workbook structures. It utilizes a logic engine compatible with industry standards to evaluate formulas and manage cell dependencies. The project provides a comprehensive suite of specialized toolkits, including a financial calculation library for bond pricing and net present value, and an engineering math toolkit for complex number arithmetic and Bessel functions. It also features a web-based spreadsheet interface for creating and formatting workbooks. The engine covers a broad
