# CSV to Chart

Category: Developer

## How do you turn a CSV into a chart?

A CSV to chart tool reads the header row, finds numeric columns, and plots each later row as a bar, line point, or pie slice. Paste or upload your CSV, map a label column and value series, then download the finished chart as SVG or PNG.

This chart maker handles comma, semicolon, tab, and pipe-separated files, including quoted fields with embedded delimiters. It detects the separator and numeric columns locally, so spreadsheet exports and private reports never need to leave your browser.

Use a bar chart to compare categories, a line chart for ordered change, and a pie chart when one positive series represents parts of a whole.

## How to use it

1. **Add your CSV** - Paste data with headers, upload a CSV or TSV file, or load the example.
2. **Map the columns** - Choose bar, line, or pie, then select the label column and one or more numeric value series.
3. **Export the chart** - Check the live preview, then copy its SVG markup or download the chart as SVG or PNG.

## Who it's for

- **Analysts** checking survey, sales, or campaign exports without opening a spreadsheet application.
- **Students and teachers** turning small experiment tables into clear charts for notes, reports, and presentations.
- **Developers** inspecting test fixtures, logs, and generated CSV files before adding them to a dashboard.
- **Small teams** creating a quick PNG for a slide or an editable SVG for a document.

## Expert note

A pie chart is only meaningful when one nonnegative series forms parts of a total. For time trends or values that can fall below zero, a line or bar chart preserves the comparison without implying a whole.

## Frequently asked questions

### Is my CSV uploaded anywhere?

No. CSV parsing, column detection, chart rendering, and export all run locally in your browser. The file or text you add is not sent to a chart service or stored in an account.

### Is the CSV chart maker free?

Yes. You can paste or upload CSV, switch chart types, select columns, and download SVG or PNG without signing up or paying. There is no watermark on the exported chart.

### How many rows can I chart?

The parser can read larger files, but the preview plots the first 60 data rows to keep labels and marks readable. For a clearer result, filter or summarize a large dataset before charting it.

### What CSV formats are supported?

The tool accepts comma, semicolon, tab, and pipe delimiters. Auto-detect checks the first complete record, and quoted values can contain delimiters, line breaks, and escaped double quotes.

### Which chart type should I choose?

Use bars to compare categories, lines to show change across an ordered axis, and pie slices for positive values that make up one whole. A pie chart rejects negative values because they cannot represent a share of a total.

### Can I chart more than one numeric column?

Yes. Bar and line charts can show up to four numeric series together. Pie charts use one series at a time so every slice has a clear label and a meaningful percentage.

### Can I use the exported chart in a presentation?

Yes. Download PNG for slides, email, and documents, or SVG when you need a sharp scalable graphic that can be edited in vector design software.
