Hi Mohamed Attia,

I'd be happy to help you with changing the numbers in Excel 2007 from English writing to Arabic numbers. Here are the steps you can follow:

1. Open your Excel sheet and select the cells that contain the numbers you want to change.
2. Right-click on the selected cells and choose "Format Cells" from the drop-down menu.
3. In the "Format Cells" dialog box, select the "Number" tab.
4. From the "Category" list, select "Custom."
5. In the "Type" field, enter the following code:
   Formula:

   0.00;[Red]-0.00;0.00;@ 

6. Click "OK" to apply the changes.
7. Your numbers should now be displayed in Arabic format.
