Spark Lines in Excel serve as small charts that you can embed within cells to observe data trends and charts simultaneously on the same table. While you may be familiar with using Charts in Excel, you might know little about Sparklines.
This article provides guidance on how to use Sparklines in Excel spreadsheets.
Step 1: You need to open an Excel file containing the numerical data you want to graphically represent trends for. Then, select the Excel cell where you want to place the Sparklines. Go to the Insert tab and under Sparklines, choose the type of chart you want to draw, for example, select Line.

Step 2: In the Create Sparklines dialog box, input the data cells you want to chart in the Data Range section. The Location Range denotes the cell that will contain the chart.
You can select data to draw multiple charts simultaneously within the Data Range and its corresponding Location Range.
Then press OK.

The charts will appear within the cells you specified in the Location Range.

To change the chart type, select the chart you want to modify, then go to the Design tab and choose a type from the Type dropdown.
