Template library
Start from a real spreadsheet
Sales, attendance, weight and finance datasets in the exact layout people export. Pick one and it appears in the editor above — no file to download, no account to create.
Sales
Monthly sales report
Six months of revenue against target — the layout most sales exports already use. Load it and switch between bar and line.
- Columns
- Month, Revenue, Target
- Look for
- Revenue overtakes target in April and stays above it, so the gap is a trend rather than a one-off.
Loads straight into the editor aboveAttendance
Team attendance
Per-person present, absent and late days for one month. A grouped bar keeps all three series directly comparable.
- Columns
- Employee, Present, Absent, Late
- Look for
- Sam has the widest gap between present and absent days, while Mei took no absences at all.
Loads straight into the editor aboveWeight
Weekly weight log
Ten weekly weigh-ins from a tracking app. Paste the same two columns and the line chart redraws as you type.
- Columns
- Week, Weight (kg)
- Look for
- The trend is down about 2.9 kg over ten weeks, with a small rebound in week four.
Loads straight into the editor aboveFinance
Income vs expenses
Six months of income and spending side by side. The grouped layout makes the surplus visible month by month.
- Columns
- Month, Income, Expenses
- Look for
- Every month stays in surplus, but margins tighten in April when expenses peak at 4,360.
Loads straight into the editor above
Every template is plain CSV with a header row. Replace the rows with your own and the chart updates as you type; nothing is sent anywhere.
How it works
Four steps, no setup
- Copy the CSV text or drop the .csv file into the editor

- Download PNG, SVG or PDF, or copy the image straight to your clipboard
Privacy
Your file never leaves your device
Parsing, binning and rendering all happen in your browser with no network request. That is also why the chart appears instantly instead of after an upload round-trip.
FAQ
CSV to Chart questions
- Do I need to upload my CSV file anywhere?
- No. Parsing and rendering happen entirely in your browser, so the file never leaves your device.
- Are semicolon-delimited CSV files supported?
- Yes. Comma, semicolon and tab delimiters are all detected automatically, along with quoted fields containing commas.
- Is converting CSV to a chart online really free?
- Yes, completely. Paste or drop the file, choose a chart type and export PNG, SVG or PDF — no account, no watermark and no usage limit.
Chart types
Chart your CSV data as…
- Bar Chart CreatorPaste any two-column list of categories and values. The bar chart renders while you type — no wizard, no configuration, no account.
- Line Graph GeneratorBuilt for time series. Paste dates, years, months or quarters in the first column and any number of value columns after it.
- Histogram BuilderPaste one column of raw numbers. FastChart bins them automatically using Sturges’ rule, and you can override the bin count with a single slider.
- Pie Chart MakerTwo columns are all it takes: a label and a value. Percentages are calculated for you and rendered directly on the slices.
- Donut Chart MakerA donut chart is a pie chart with the centre cut out — perfect for dashboards where the middle holds the headline total.
- Scatter Plot MakerPaste two numeric columns — X first, then Y. FastChart detects that both columns are numeric and switches to a scatter plot automatically.
- Radar Chart MakerAlso called a spider chart. Put the dimension names in the first column and one column per item you want to compare.
- Area Chart MakerAn area chart is a line chart with the region below filled in — good for showing volume over time and cumulative totals.
- Bubble Chart MakerA bubble chart is a scatter plot with a third variable encoded as the area of each point. Paste an X column, a Y column and a size column.
- Stacked Bar Chart MakerA stacked bar chart shows the composition of each total. Every numeric column becomes a segment stacked on top of the previous one.
- Grouped Bar Chart MakerA grouped (clustered) bar chart puts the series side by side so every bar shares the same baseline and stays directly comparable.
- Treemap GeneratorA treemap encodes each value as the area of a rectangle. It handles far more categories than a pie chart without becoming unreadable.
- Funnel Chart MakerA funnel chart shows how many items survive each stage of a process. Paste the stages in order, from widest to narrowest.
- Waterfall Chart MakerA waterfall chart breaks a net change into its parts. Paste a label column and a column of positive and negative changes — the running total is calculated for you.
- Polar Chart MakerA polar (radial bar) chart wraps a bar chart around a circle. It is compact and eye-catching for a modest number of categories.
- Heatmap GeneratorA heatmap shades a grid of values from low to high. Paste a table where the first column labels the rows and every other column is a heatmap column.
- Candlestick Chart MakerA candlestick chart shows the open, high, low and close of each period in a single mark. Paste five columns: a date plus OHLC.
- Box Plot MakerA box and whisker plot summarises a distribution: the box spans the interquartile range, the line is the median, and points beyond the whiskers are outliers.
- Violin Plot MakerA violin plot draws a mirrored density curve for each group, so you can see bimodal and skewed distributions that a box plot would hide.
- Gantt Chart MakerA Gantt chart lays every task on a shared time axis so overlaps and dependencies become obvious. Paste a task name, a start date and an end date.
- Timeline MakerA timeline places events on a single date axis with alternating labels. Paste a date column and a label column — the rows are sorted for you.
- Sunburst Chart MakerA sunburst chart shows a hierarchy as concentric rings — the centre is the root and each ring out is one level deeper.
- Network Graph MakerA network graph draws entities as nodes and relationships as edges. Paste a source column, a target column and an optional weight.
- Sankey Diagram MakerA Sankey diagram shows flow between stages, with band thickness proportional to volume. Paste three columns: source, target and value.
- Chord Diagram MakerA chord diagram arranges entities around a circle and connects them with ribbons whose width shows the volume flowing in each direction.
- Hexbin Plot MakerA hexbin plot solves overplotting: instead of drawing thousands of overlapping dots it bins them into hexagons shaded by density.
