How to use it
- Two columns: names, then values; there is no need to work out percentages first.
- With more than six categories, set Max slices to merge small ones into Other.
- Use a donut when you want space for a total or label in the middle.

Frequently asked questions
How do I bring in data from Excel?
Select the range including headers in Excel, WPS or Google Sheets, copy and paste it into the data box; tabs are detected automatically, and CSV or comma- or semicolon-separated text works too. Thousands separators, currency symbols and percent signs are removed.
Is there a watermark? Can I put it in PowerPoint?
No watermark. PNG exports at twice the chosen size and SVG is vector, so both stay sharp in PowerPoint, Word or print; you can also copy the image and paste it directly.
Is my data uploaded?
No. Data is parsed and drawn in your browser. A share link carries the data after the # in the URL, which is never sent to the server; only people with the link can see it.
How are the percentages calculated?
Each slice's percentage = its value ÷ the sum of all positive values × 100%; rows with the same name are added together and negative values are ignored with a note.
What if there are too many categories?
Pie charts get hard to read beyond six or seven slices. Use "Max slices" to merge the small ones into "Other", or switch to a horizontal bar chart.
