A shared Excel table is used as an example to illustrate the use of SDK. The same applies to other application scenarios.
The following description shows how multiple people can collaboratively fill in a spreadsheet at the same time within an organization:
```javascript
WXAPI.newsExtFieldDynamicV2({
token: '000'
})
```
+ token current user login credentials
+ newsId is the ID of the spreadsheet. The interface obtains changes in all cells in this spreadsheet.
Regularly train this interface (it is recommended to request it every 3 to 5 seconds). After obtaining the changed cell list, compare it with the local version (version number) of the cell. If it is higher than the local version number, it means that someone has changed the value of the cell and overwritten it.
