Before starting a complex coding project, it’s always best to have a visual idea of workflows and systems. When you give a structure to sprawling projects, you cut down on noise, remove inaccuracies, and achieve completion before deadlines.
And that’s what a flowchart is—a visual representation of processes. You can use it for complex projects requiring visual cues, including coding sprints.
For developers, flowchart loops indicate repetitive tasks that can be looped to save time. Depending on the way reiterations are set, flowchart loops can be of two types: for loop and while loop.
In this article, we’ll review the concept of for loop flowcharts and show you how to create one.
How to Create a For Loop Flowchart
Understanding For Loops
A for loop flowchart allows programmers to run a specific line of code multiple times with a control statement and a body of instructions. It’s used when the programmer knows in advance how many times the codes must be executed to meet the conditions.
For example, if you run an offer where you give away gift cards to the first 50 users who sign up for your website, the for loop repeats exactly 50 times.
With for loop, you can:
- Run the same task for a fixed number of times
- Iterate list, dictionary, and other collections of items one at a time
- Avoid code repetition for clean and compact lines
The difference between for loop and while loop
A while loop flowchart helps you run repetitive processes, like a for loop flowchart. However, it differs in its approach to controlling flow statements.
If you don’t know how many times codes need to run but know specific conditions that must be met for codes to keep running, you can use a while loop for efficiency.
Let’s take the giveaway example.
This time, you want to send $20 gift cards to early adopters but don’t know how many would sign up and when. You’ve set aside $500 worth of gift cards for this campaign.
With a while loop, you can run codes that send $20 gift cards until the budget is exhausted. You don’t know for sure how many times it will run, but the condition is that it can’t exceed the $500 budget.
Here are the key differences between the for loop and the while loop:
For loop | While loop |
Programmers know how many times codes need to be executed | Programmers know what conditions must be met for the loop to continue but not necessarily how many times it’ll run |
Usually runs through explicit collections like strings and dictionary | The loop continues as long as the condition is “true” |
For loop ends when the predefined number of iterations is reached and doesn’t trigger an infinite loop | The while loop continues to run indefinitely unless the condition becomes “false” |
Ideal for straightforward and repetitive tasks | Ideal for complex and dynamic conditions |
Components of a For Loop Flowchart
Despite the relative simplicity of for loops, it’s important to know the components that make the flowchart.
- Initialization: This is the loop control variable that runs only once at the beginning
- Condition: It’s tested to verify if it’s true or false. In the giveaway example, the condition is whether 50 people have been given the gift cards
- Decision point: It’s when the condition verification decides the next step. If it’s “true,” it continues to execute
- Loop body: The loop body is used to run all the statements
- Update: The loop continues to be updated based on the decision point
- Increment/Decrement: The update is either incremental or decremental. For the giveaway example, the number of customers who receive gift cards continues to increase until it hits 50
How to Create a For Loop in Flowchart
We’re going to show you how to create a for loop flowchart in Microsoft Excel. First, open a new Excel sheet and give it a name.
Step 1. Initialize loop control variable
- Click on Insert > Shapes to open shapes collections and scroll down to find basic flowchart shapes
- Click on the oval shape (Flow chart: Terminator) to add to Excel
- Click on Shape > Fill to paint it yellow
- Double-click the shape to add labels for the initialization step. For example, ‘Start sending gift cards’
Step 2. Condition check
- Insert a diamond shape for the condition, fill green color, and label it appropriately by following the process above. The condition in this case would be: Gift cards <50?’
- Go to Insert > Shapes and pick the arrow from the Lines collection to connect two shapes
Step 3. True path
- Draw an arrow from the condition to a rectangle (Flow chart: Process) for the loop body if the condition is true
- Fill the rectangle using blue color
- Click Insert > Text Box to add a text box beside the arrow
- Double-click the text box to write True
Step 4. Loop body
Label the rectangle with the actions to be repeated. For instance, ‘Send another gift card’
Step 5. Update step
- Add another rectangle to update the loop control variable. Example: ‘Increase the number of shared gift cards by 1’
- Connect the loop body, update, and condition with an arrow and elbow arrow connector
Step 6. False path
- Insert a rectangle to signify the end of the loop
- Fill it with white color
- Draw a line from the condition to the endpoint if the condition is false
- Add a text box beside the arrow to write “False’
Based on these steps, the for loop flowchart should look like this:
While you can use tools like Excel to create flowchart loops, it doesn’t offer extensive lists of pre-made structures or scalable features that can be used regularly and without friction. One of the best ways to bring these ideas to life is by using flowchart templates built specifically for custom use cases.
Using to create flowcharts
As a business workflow software, features carefully designed flowchart creation tools such as Whiteboards and Mind Maps to help you complete projects. It excels (pun intended) at keeping things simple, visually appealing, and connected to your workflows.
Whiteboards is the visual playground for collaborators and creatives. Team members can freely add ideas or concepts to overall strategies, which helps build accountability.
Users can choose from one of many process workflow templates or start from scratch. The whiteboard’s left menu bar houses all the tools to help you customize your board. Add shapes, colors, and text to mark different elements in your flowchart, and use the connectors to build relationships—all within a drag-and-drop space.
But looking pretty is not the only good thing about Whiteboards. It goes beyond traditional tools by offering scalability and real-time collaboration.
For example, you can brainstorm and strategize with colleagues by adding Docs and Tasks to the mix. You can even embed Items such as people and lists to enrich your flowcharts with more data points.
This also extends to content from outside of . Be it a Figma design, a Google spreadsheet, a YouTube video, or a website link, you can add various types of content that make your projects detailed and authentic.
On top of that, you can use pre-made layouts such as process map templates to create visual clones of complex SOPs and reduce errors.
Steps to create a for loop flowchart in Whiteboards
By using the tools discussed above, you can draw a for loop flowchart quickly within .
In your Workspace, expand the left sidebar by clicking More and then select Whiteboards. Name the whiteboard and select a template that suits your needs. To illustrate this flowchart, we selected the Start from Scratch button.
Step 1. Initialize loop control variable
- Click the shape icon from the left menu bar and select the circle
- Draw an oval by modifying the circle
- Click the Fill Color icon over the shape to paint it yellow
- Click the T icon next to it to label the oval with the initialization step. For example, ‘Start sending gift cards’
Step 2. Condition check
- Draw a diamond shape for the condition, fill green color, and label it. The condition is ‘Gift cards <50?’
- Select the Connectors icon from the left menu bar and connect the two shapes
Step 3. True path
- Draw a line from the condition to a rectangle for the loop body if the condition is true
- Fill the rectangle with blue
- Click the T icon over the line to write ‘True’
Step 4. Loop body
Label the rectangle with the actions to be repeated. In this case, it’d be ‘Send another gift card’
Step 5. Update step
- Draw another rectangle to update the loop control variable. Example: ‘Increase the number of shared gift cards by 1′
- Connect the loop body, update, and condition with connectors
Step 6. False path
- Add a rectangle to signify the end of the loop
- Fill it with white color
- Draw a line from the condition to the endpoint if the condition is false
- Click the T icon over the line to write ‘False’
Based on these steps, the flowchart should look like this in :
While Whiteboards is the ideal way to draw diagrams and flowcharts, you can pair it with Mind Maps for granular understanding. Mind Maps are easy-to-create idea chains where each idea is represented through nodes. These nodes branch off in different directions, helping users manage time and productivity.
The Project Mapping Flowchart Template is one of the easiest ways to create and modify mind maps based on project complexities.
With this template, you can add tasks with mind map nodes, get a holistic understanding of every component of the project, and stay on track.
Here’s how you can use the template to visualize your project:
- Use Tasks to add steps and responsibilities required to finish the project
- Add custom statuses and update them on every step to maintain clarity
- Switch between Ideas, Getting Started Guide, and Project Plan Mind Map views to help teammates understand tasks and roles
When you have so many layers of steps and stakeholders, bringing them all together on a dashboard helps companies mitigate data inaccuracies and time wastage.
By using Whiteboards and Mind Maps in tandem, assignees can understand how they’re connected to the larger project, enabling them to work cross-functionally.
Example For Loop Flowchart
Flowchart loops in Python work with collection-based iterations. For example, numbers, strings, and dictionaries are easy for loop execution.
Example in Python
This structure below clearly shows the loop process: initialization, checking the condition, printing the value, updating, and repeating until the condition is no longer satisfied.
Code Example: for i in range(0, 10): print(i)
Flowchart Representation:
Start
Initialize i = 0
Condition i < 10
True Path: print(i)
Increment i = i + 1
Repeat Step 3
False Path: End
Based on the loop flowchart outline, it’d look like this in Python:
Benefits of Using Flowcharts for For Loops
Looping in flowcharts is a game-changer, especially for the computer programming process. If you aren’t already using it, here are some benefits you’re missing out on:
Visual clarity
A flowchart loop gives you a visual reference to how the codes should be executed. As coding sprints grow in complexity, the ability to refer back to a structure saves you several hours of productivity.
Since the loop’s logic is illustrated with shapes, colors, and arrows, it’s easy to understand and explain step-by-step tasks, especially to non-programmers.
Debugging and optimization
By following the execution path, you can detect if something’s wrong. You can also remove logical errors and optimize the codes before running them.
When you have optimized codes, you can deploy them to business use cases like calculation and computation that require iterations.
Better communication
By following a for loop flowchart, team members can maintain transparency of knowledge and consistency in communication.
The extensive documentation means it’s more compliant with security policies while assisting in internal training.
Code maintenance
For legacy codes, flowcharts are lifesavers. Even if there’s a knowledge gap, code flowcharts can help you understand code logic, making it easier to maintain or modify it for years.
Chart Your Project Path With
To maximize the benefits of for loop flowcharts, you must create them right at the beginning. But if you’re not sure of how many times you need to execute codes, while loop flowcharts will come in handy.
You can create a basic flowchart in Microsoft Word if you want something rudimentary. However, it’s better to go with a tool that’s purpose-built to solve this problem.
’s brainstorming and collaboration tools are designed to plan and execute complex projects with visual cues. From process mapping to programming projects, the mind maps and whiteboards will help you work efficiently without jumping between several apps.
