zSheet

zSheet is an open-source spreadsheet component and data grid intended for embedding into web applications. It provides a spreadsheet-like editing experience and data manipulation capabilities within a lightweight, framework-agnostic library. The project aims to offer a balance between a familiar user interface and a modular, embeddable architecture suitable for dashboards, forms, and data entry tools.

Key features commonly associated with zSheet include a cell-based data model, a built-in formula engine supporting common functions, rich cell formatting options, and essential data operations such as sorting, filtering, and grouping. The library supports import and export of common data formats (for example CSV and JSON) and includes undo/redo support. A plugin or extension system allows developers to customize behavior, renderers, validators, and interactions without altering core code.

Architecture and design emphasize modularity and extensibility. The core engine handles data storage and evaluation, while a rendering layer presents the grid or spreadsheet UI. API surfaces expose programmatic control over cells, ranges, and events, enabling integration with other UI components. Community bindings and wrappers aim to simplify integration with popular front-end frameworks.

Licensing and development are typically governed by an open-source model, with a public repository and contribution guidelines to encourage collaboration, issue tracking, and feature requests. The project’s ecosystem often includes example applications, documentation, and community-created plugins to illustrate common use cases and integration patterns.
