About this tool

A small tool, built honestly.

csvtodashboard exists because every other "CSV visualizer" online wanted an email address, a signup, a paid tier, or all three — before showing a single chart. This one just turns your spreadsheet into a dashboard. That's the whole thing.

What it does

The whole feature list, here.

No surprises, no upsells. If something doesn't appear on this list, it's not in the tool.

  • 01

    Reads CSV and Excel files

    .csv, .xlsx and .xls. Multi-sheet workbooks let you pick which tab to load. Files up to ~50 MB.

  • 02

    Auto-builds a dashboard

    KPIs, time-series chart, category breakdowns, distribution histograms, scatter plot with correlation when two numerics relate, and a sortable data table with semantic formatting (currency, percent, dates).

  • 03

    Detects column meaning

    Recognizes column roles by name — revenue, units, percent, rating, email, country, status — and formats values accordingly.

  • 04

    Click to filter, drag to brush

    Click any chart bar or donut slice to filter the whole dashboard. Drag on the time chart to zoom into a date range.

  • 05

    Flags outliers and top movers

    Rows more than 2σ from the mean get an orange border. Time-series data gets a top-gainer / biggest-decline callout.

  • 06

    Writes plain-English insights

    3 deterministic observations about the data on every load — concentration, trend, outliers, correlations. No AI, no API calls, no costs.

Who built it

One person, a few weekends.

Built by Cem, originally as a side project to learn React deeper. It turned into something genuinely useful for the kind of CSV file you'd otherwise stare at in Excel for 20 minutes. If you want to reach me about a bug, a feature, or a typo, email is the fastest way.

  • ·

    One-click PDF export

    Today: browser print-to-PDF works well (the layout is print-friendly). On deck: a single button that produces a polished multi-page report.

  • ·

    Multi-file join

    Drop two CSVs, pick the shared key column, get a joined dashboard. Common ask for sales + inventory or orders + customers.

  • ·

    More chart types

    Heatmap (day × hour for timestamped data), treemap (nested categories), funnel (status pipelines), stacked area (category split over time).

  • ·

    Real choropleth map

    Today: bubble map for country/state columns. On deck: proper colored country/state shapes using world-atlas TopoJSON.

    This isn't a roadmap item — it's a principle. The tool stays signup-free. If you want to save a dashboard, use Export HTML or the share link.
