How to use CSV Chart Generator
- 1
Drop your CSV
Drag a .csv or .tsv file onto the dropzone. PapaParse reads it in your browser — nothing is uploaded.
- 2
Pick a chart type
Choose Bar for category comparisons, Line for trends over an ordered axis, or Pie for shares of a whole. You can switch types at any time without re-loading.
- 3
Pick the label and value columns
The label column (X) holds the categories or dates; the value column (Y) holds the numbers. The tool auto-guesses a sensible pair on first load.
- 4
Choose an aggregation
When labels repeat, pick Sum, Average, or Count to collapse them into one point per label. Pick None if each row is already a distinct point (for example, daily revenue rows).
- 5
Export the chart
Click Download SVG for a resolution-independent vector (paste into Figma, Keynote, or a blog post) or Download PNG for a 2× raster image. Colors and axes travel with the file.
Frequently asked questions
- Does this tool upload my CSV?
- No. Every parse, transform, and download runs entirely in your browser using JavaScript and Web Workers. The file never leaves your device — there is no upload endpoint and no server-side processing.
- Why are only the top values shown for big datasets?
- The chart caps at 50 data points so bars and labels stay readable. Everything above the cap is either clipped (bar and line charts) or grouped into an 'Other' slice (pie charts). For full-fidelity output, aggregate first with CSV Column Statistics, then chart the result.
- What counts as a numeric column?
- The tool treats a value column as numeric when at least 80% of its non-empty cells parse as a number. Booleans are coerced to 0/1 so you can chart true/false rates without pre-processing.
- Is PNG export lossless?
- PNG is rasterized at 2× the visible size, which looks sharp on Retina displays but is still a raster. For infinite zoom (slides, print), prefer the SVG download — it opens in Figma, Illustrator, and Inkscape.
- Can I chart negative values or dates?
- Yes — bar and line charts handle negative values with an auto-placed zero line. Dates are plotted in the order they appear in the CSV, so sort your file first with CSV Sort if you need strict chronological order. Pie charts ignore negative values since a slice can't be less than zero.
