Free Online Mini BI Tool — Turn Your CSV or Excel File Into an Interactive Dashboard

Upload a CSV or Excel (.xlsx/.xls) file and get charts, KPIs, click-to-filter, and a searchable row browser — built automatically from your columns. Works smoothly on up to 2,00,000 rows, entirely in your browser.

▸Why use FYX Data's Mini BI tool

Most spreadsheet-to-dashboard tools ask you to upload your file to a server, sign up for an account, or install desktop software before you see a single chart. FYX Data's Mini BI tool skips all of that — pick a CSV or Excel file, and the dashboard builds itself from your actual column headers, right inside this browser tab. It's meant for the quick, one-off dashboard you need for a report or a review, not for replacing a full analytics stack.

Because the file is read and processed on your device, there's nothing to configure for privacy or compliance — the data simply isn't sent anywhere. This makes it useful for sales reports, inventory sheets, survey exports, attendance logs, or any spreadsheet where you want a fast visual read before deciding whether it's worth a deeper analysis.

  • Automatic column detection — numbers, categories, and dates are identified for you.
  • Click-to-filter charts, with undo/redo across every change.
  • Multiple dashboard pages, up to 8 widgets each.
  • Export your filtered data back to CSV or Excel, or a PDF snapshot of the dashboard.
▸How to use this tool
  1. Upload — drop a CSV or Excel (.xlsx/.xls) file, or tap "Try it with demo sales data" to explore the tool first.
  2. Configure — the tool auto-detects your columns and pre-selects a useful mix of widgets. Tick or untick any widget, up to 8 per page, then save the page.
  3. Explore — click any bar, pie slice, or segment to filter the whole dashboard. Use Undo/Redo to step through changes, and add more pages for extra widgets.
  4. Search — scroll down to Step 4 to search and browse the raw rows behind your dashboard.
  5. Export — download your filtered data as CSV or Excel, or export a PDF snapshot of the current dashboard page.

Frequently asked questions

▸Is my CSV or Excel data uploaded to a server?
No. Every step — reading the file, building charts, filtering, and searching — runs inside your browser tab using JavaScript. Your file is never sent to FYX Data or any other server.
▸What file formats does the Mini BI tool support?
You can upload .csv files or Excel files in .xlsx or .xls format. The tool automatically reads the first sheet of an Excel workbook and detects your column headers.
▸Is there a row limit?
Yes, the tool is capped at 2,00,000 rows to keep charts and filtering smooth inside a browser tab. If your file has more rows, you can choose to load the first 2,00,000.
▸Can I export the dashboard I build?
Yes. You can export your current (filtered) data back to CSV or Excel, or export a PDF snapshot of your dashboard's KPIs and charts.
▸Do I need to sign up or install anything?
No. The Mini BI tool works directly in this page — there is nothing to install and no account is required.
▸Does this replace a full BI tool like Power BI or Tableau?
No — it's built for quick, one-off dashboards from a single CSV or Excel file, right when you need one, without setting up a full BI workspace.
