To successfully create a sparkline in Microsoft Excel, the following steps should be followed in this order:
Select the cell near the data you want to use.
Go to the "Insert" tab.
In the "Sparklines" group, select the sparkline of your choice.
In the "Create Sparklines" dialog box, enter the data and location ranges for the sparkline.
Click "OK" to create the sparkline.
Alternatively, you can also create a sparkline using the "Sparkline" function in the formula bar. To do this, enter the function and its arguments in the formula bar, and then press Enter to create the sparkline.
For example, to create a line sparkline using data in cells A1:A10 and placing the sparkline in cell B1, you would enter the following formula in the formula bar:
=SPARKLINE(A1:A10, {'charttype', 'line'})
Then, press Enter to create the sparkline.
