CSV Data Visualizer
Free online CSV data visualizer. Upload any CSV file and generate interactive bar charts, line charts, scatter plots, pie charts, histograms, and more. Configure axes, aggregations, and color palettes. Export charts as PNG or SVG. Runs entirely in your browser — your data never leaves your device.
What is CSV Data Visualizer?
CSV Data Visualizer is a free, browser-based tool that turns raw CSV data into interactive charts instantly. Upload any CSV file or paste data directly, pick a chart type, map your columns, and see your data come to life.
All processing happens entirely in your browser using JavaScript — your data never reaches any server. There is no file size limit imposed by a backend, no account required, and no privacy risk. It works with any standard CSV export from Excel, Google Sheets, databases, or data pipelines.
Once your chart is ready, export it as a high-resolution PNG for presentations or an SVG for print and further editing in tools like Figma or Illustrator.
Frequently asked questions
Does my CSV data get uploaded to a server?
No. All parsing and chart rendering happens entirely in your browser using JavaScript. Your data never leaves your device.
What CSV formats are supported?
Any standard CSV with a header row. The tool auto-detects comma, semicolon, and tab delimiters, handles quoted fields containing commas, and infers numeric vs. string column types automatically.
Can I export the chart?
Yes. Use the Export PNG button for a 1200×700 raster image great for presentations and documents, or Export SVG for a resolution-independent vector file you can edit in Figma, Illustrator, or Inkscape.
Is there a row limit?
There is no enforced limit. For best performance we recommend keeping CSVs under 50,000 rows. Use the aggregation option (Sum, Average, Count) to collapse large datasets into summary views.
What chart types are supported?
Bar chart, line chart, scatter plot, pie chart, area chart, histogram, donut chart, box plot, heatmap, and bubble chart.
Can I use this to visualize database query results?
Absolutely. Export your query results as CSV from any database client (DBeaver, TablePlus, psql \copy, etc.), then upload here to generate charts instantly.
