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.
To add this new feature to your web application, please refer to ZK Spreadsheet Essentials - ZK Spreadsheet/Collaboration Edit
Data validation helps users in editing and verifying cell values to ensure data accuracy and consistency. It also allows you to do the following:
- Prompt message: Create a prompt message that explains the data type of the cell
- Validation list: Make a list of the entries that restricts the values allowed in a cell
- Incorrect message: Pop-up an incorrect message dialog when incorrect data has been entered

New Chart Types
ZK Spreadsheet 2.2 introduces us a variety of new chart types, improving end user experience offering more choices of presentation for their data including;
Locale-aware date/number input & output

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
