Whenever we talk about product ratings & customer satisfaction, 5 star ratings come to our mind. Today, let’s learn how to create a simple & elegant 5 star in-cell chart in Excel. Something like this:

A while ago, Hui showed us a fun way to create 5 star charts in Excel using bar charts with 5 star mask. I highly recommend reading that article if you want to create a regular chart version of this.
Tutorial for creating a 5 star chart
1. Meet the data
Here is our data. Very simple. First column has product names. Second column has customer rating – from 1 to 5.

2. Set up 5 blank columns for the 5 star chart
Let’s create a 5 column grid right next to our data set. This is where the in-cell 5 star chart will go. At this stage our 5 star chart looks like this:

If you haven’t guessed yet, we will be using conditional formatting > star icons to get the 5 star chart.

3. Write formulas in the 5 column grid
Now, we need to write formulas to fill up the 5 column grid. We need to formulas to return either 1, 0 or decimal values in the grid depending on the rating for that row.
So, for example, if a product has 3.30 rating, we want to print 1, 1, 1, 0.30 and 0 in 5 columns.
You can use any number of formulas to get this result. The simplest one will be IF formula.
Assuming column C (from C7) has product ratings & row 5 has running numbers 1 to 5 (from cell D5), we can use below formula to get what we want:
=IF(D$5<=$C7,1,IF(ROUNDUP($C7,0)=D$5,MOD($C7,1),0))
To understand the above formula , see this illustration.

If you like to avoid IF formulas, here is an alternative:
=MAX(($C7>=D$5)*1,MOD($C7,1))*(ROUNDUP($C7,0)>=D$5)
A challenge for you: Can you think of any other ways to write this formula?
4. Apply conditional formatting to the 5 column grid
Select the 5 column grid and apply conditional formatting (Home > Conditional Formatting > New rule)
Set up the rule as shown below:

At this stage, our report looks like this:

5. Adjust column width and borders
Once the formatting is applied, just clean up the report by adjusting column width (set it to 24 px) and add horizontal borders only.
And our product rating report is ready.

How would you visualize customer ratings in Excel?
While 5 star charts are traditional, they dumb-down the data. Can you think of other fun ways to visualize customer / product rating data? Please share your thoughts & implementations in the comments.

Hello...
In Power BI I have data that includes months by name only (e.g. May, April, December...)
I need to build charts etc. but i need the months to go chronologically... not alphabetically... I cannot seem to find the fix to this.... once again, my data does NOT have an actual date attached to it (like 02/01/2023)....only month names... can i use a helper table wher i id the month names as numbers 1 thru 12? and if so, how do i manage this to work for me ?
Thank you.

You need to setup an extra table to map each month name to a running number. A simple 12 row table like
Jan 1
Feb 2
Mar 3
..
Dec 12
Then create a relationship between this month table and your month column
Now, go to "table view" in Power BI and set the sort by column to month number for the month name column on this new table.
Finally, use the new table's month name whenever you need to refer to the month name in the visuals.
They will be chronologically arranged.
