When you create a text box in your document Excel, any text you type appears has the default font that can be different from version to version...

A flow chart usually shows steps in a task, process, or workflow. There are many different SmartArt templates predefined in Excel that you can use to illustrate the process, including some complex templates with pictures.

A flowchart or flow chart usually shows steps of the task, process, or workflow. There are many different SmartArt templates predefined in MS Excel that you can use to illustrate the process, including visually appealing templates with pictures.
However, if you want to use different shapes and a complex topology, it is better to create your own flowchart:

Most process flow diagrams and workflow charts use elbow connectors for connecting process stages and elements, but too many connecting lines of the same type give your chart a messy look. Fortunately, you can combine different connector types that represent semantically different transitions.

When you create the process flow chart, process map, business flow diagram or data flow diagrams and UML activity diagrams you often need to add some text or labels to the connectors. Unlike other free and commercial diagram drawing packages, Microsoft Office shapes provide extremely rich text formatting features.

Business process charts like employee routines, document preparation, and approval, or online user navigation path on a website or a Web store are different from academic flows of algorithms. Usually, academic applications use a limited number of standard shape types, but in business, different shapes give a better look and simplify understanding. However, it is hard to decide which shape is appropriate for the specific block.

The Format tab of the Shape Format tab (the Drawing Tools toolbar in the previous version and Excel 2016) provides a plenty of options for customizing a shape outline, background, and text settings. Also, you can change spacing and size for multiple shapes at once.

Every time you add, move, or resize shapes, by default, it isn't easy to align them. Excel proposes features named Snap to Shape and Snap to Grid that can help to organize shape and any objects.

By default, gridlines are displayed in worksheets using a color that is assigned by Excel. But if you want, you can change the color of the gridlines for a worksheet (see also How to turn on and turn off gridlines in Excel and How to change width of gridlines in Excel).

Gridlines help you align shapes and create consistent dimensions for each object. In Excel, gridlines are simulated by column borders, and changing column widths and heights essentially controls your gridlines.
