SpreadJS v13.2 official version download
Recently, I have paid attention to a hot question on "Zhihu": What online document editing software is similar to Google Docs in China? Everyone's replies are basically around mature online document editing software, such as Graphite Document, Tencent Document, Youdao Cloud Collaboration, etc., each of which has its most suitable usage scenarios, and some focus on data storage and data security. Some focus on team management and document collaboration. For end users, there are many types of mature online document editing software products on the market, but only the one that best suits the business needs is the best.
In view of different business needs, the direction users pay attention to is also very different:
- Large companies pay more attention to data security, collaboration efficiency, and compatibility with original system documents
- Small and medium-sized companies pay more attention to authority control, automatic backup, and data synchronization
How can we ensure the perfect fit between the system and the business? In addition to self-development, a more time-saving and labor-saving way is to use third-party components to develop a personalized "online Excel" system.
Based on this, today I will give you Amway a pure front-end development tool- SpreadJS that can meet business scenarios such as Web Excel component development, data reporting, Excel report design, online Excel collaborative editing , and share with you how to use SpreadJS The product features of "high performance, cross-platform, and high compatibility with Excel" can efficiently complete the development and maintenance of the "online Excel" system.
Difficulties in the development of "online Excel" system
The team’s requirements for document management can generally be divided into three levels: storage, management and collaboration.
A qualified online document editing software must first meet the requirements of team document storage, synchronization, and data security; secondly, it must meet the requirements of document management, that is, to achieve retrieval and authority control in a complex, multi-level document directory; finally, It is to meet the needs of multi-person teams for collaborative office. Many times a document needs to be modified by multiple people at the same time. At this time, the online collaboration function can help the team greatly improve work efficiency.
In summary, the difficulties of "online Excel" system development include:
- Storage requirements: storage space, real-time data synchronization, and data security
- Document management: authority control, document retrieval, classification and summary
- Online collaboration: multi-person online editing, data rollback, backup, comment
- Compatibility and ease of use: compatible with native Excel documents, multiple terminals are available, and low learning costs
