Introduction

ZK Spreadsheet is an Ajax component that delivers functionalities of Microsoft Excel to your browsers. ZK Spreadsheet 2.2 brings with it a host of new features including validation functionality, supporting more chart types, adding/deleting/moving/sizing charts and pictures, collaboration editing, locale-aware date/number input and output and also performance enhancement.

Collaboration editing

Collaboration editing is one of the most important features added to this release allowing a group of individuals to edit the spreadsheet file at the same time like that of Google's online spreadsheet. Prior to this release, users were able to edit but if another user is also editing at the same time, they will be competing to save as the latest version , however, users are now offered the ability to edit, add or delete the content at will and observe other users' edits in real time.

Performance enhancement

As performance is a very important aspect in enterprise level applications, enhancing performance is always one of our most critical tasks. In ZSS 2.2, we have gone through a mechanism adjustment where previously, data must be retrieved from the server-side but now, part of the cache is saved on the client-side thus optimizing the scrolling of a page. Moreover, we have also fine tuned the code to optimize page loading by 1.4 times compared to that of ZK Spreadsheet 2.1.1
