Free Pie Chart Maker — Create Pie Charts From CSV Data Online
Table of Contents
Pie charts have a reputation problem. Misused constantly in corporate decks, they've become the chart everyone loves to hate. But for the right data — showing what fraction of a whole each part represents — nothing communicates more immediately.
This free tool turns CSV data into a pie chart in seconds. Upload your file, select your label and value columns, and the chart renders right in your browser. Download it as a PNG with no watermark.
How to Create a Pie Chart From CSV Data
Pie chart data needs two things: a column of category names and a column of numeric values. The tool handles the rest.
- Prepare your CSV. You need two columns minimum: one with the slice labels (product names, regions, departments) and one with the numeric values (revenue, count, percentage).
- Upload or paste. Drop the file or paste your data directly.
- Set your X-axis column to the category/label column — this names each slice.
- Set your Y-axis column to the value column — this determines slice sizes.
- Select Pie from the chart type dropdown.
- Pick a color palette and click download. PNG, white background, no watermark.
You can also choose Doughnut for the same data — it's a pie chart with a hole in the center, which some people find cleaner and easier to label.
When to Use a Pie Chart (and When Not To)
Pie charts work when these conditions are all true:
- You're showing parts of a whole — all slices should add up to 100%
- You have 5 or fewer distinct slices (beyond 5-6 slices, readers can't distinguish them)
- The differences between slices are large enough to be visible
- You're not comparing trends over time (use a line chart for that)
Classic good pie chart uses:
- Market share by brand (3-4 major players + "Other")
- Budget allocation by department or category
- Traffic breakdown by source (Organic / Paid / Direct / Referral)
- Survey responses by answer option (Agree / Neutral / Disagree)
When to use something else:
- Comparing values between categories (use a bar chart — heights are easier to compare than angles)
- Showing change over time (use a line or area chart)
- More than 6 categories (group the small ones into "Other" first)
Pie Chart vs Doughnut Chart — Which to Choose?
Functionally identical — same data, same calculation, different visual. The doughnut has a hole in the center.
Choose pie when: You want the traditional look, the chart stands alone, or your audience is unfamiliar with doughnut charts.
Choose doughnut when: You want a more modern aesthetic, or you plan to add a number or label in the center hole (like the total count or "100%" — a common design choice in dashboards).
Both options are available in the tool under the chart type dropdown. Generate both, see which you prefer, download the one that looks better in context.
Color Palettes for Pie Charts
Color choice matters more in pie charts than other chart types, because each slice needs to be visually distinct from its neighbors. The tool offers five palettes:
- Vibrant — high contrast, works well for 3-5 slices, looks good on white backgrounds
- Pastel — softer look, works better in contexts where you want the chart to feel lighter (presentations, infographics)
- Dark — designed for dark-background documents or slides
- Monochrome Blue — shades of blue, good when you want a cohesive branded look or the chart appears alongside other blue-heavy elements
- Warm — oranges, reds, yellows — good for food, consumer, or lifestyle contexts
For most business reporting, Vibrant or Pastel on a white background is the default safe choice. For presentations with dark slides, use Dark.
Grouping Small Slices Before Creating Your Chart
If your data has eight categories, don't plot all eight. Anything under 3-5% of the total becomes a sliver that readers can't meaningfully interpret. The fix: combine small categories into an "Other" slice before building your CSV.
In your spreadsheet, sort by value (smallest to largest). Sum everything under your threshold (say, 5% of total). Replace those rows with a single row called "Other" with the summed value. Export to CSV, then upload.
A pie chart with 4 meaningful slices and one "Other" communicates more than a pie chart with 12 tiny slices that are all labeled but unreadable.
If you need to show all the detail, consider a bar chart instead — bars make it easy to compare even small differences between many categories.

Open Free CSV to Chart ToolFrequently Asked Questions
How many slices can a pie chart have?
There is no hard technical limit, but 5-6 slices is the practical maximum for readability. More than that and the slices become too small to distinguish. Group anything below 5% of total into an "Other" category.
Can I make a pie chart from percentages?
Yes. If your value column contains percentages (like 45, 30, 25), the tool will scale the slices proportionally. Make sure your percentages add up to 100 — otherwise the pie chart will either have a gap or overflow.
What is the difference between pie and doughnut charts?
They display the same data. A doughnut chart has a hollow center, which can look more modern and gives you space to add a central label or number in design tools. Functionally identical.
Is the pie chart downloaded with a transparent background?
The PNG download has a white background. If you need a transparent background version, open the PNG in an image editor and remove the white background, or use our transparent background maker tool.
