Hi @poojacha77
You can try this:

[x_spreadsheet].sheet.toolbar.boldEl.click()

@myliang Above script is working fine.But how can call toolbar dropdown functions particularily.For e.g Font,Format,Functions.

@xiujunma
Please also suggest for explicit call of following toolbar functionalities

1. format
2. font
3. fontsize
4. text color
5. fill color
6. border
7. horizontal align
8. vertical align

functions

Thanks
