How this works
Before building a dashboard on top of a file, it's worth knowing what's actually in it: which columns are mostly empty, which ones barely vary (not useful for a chart), and whether there are duplicate rows quietly inflating totals. This reads your file, profiles every column — type, completeness, distinct-value count — and gives a quick 0–100 quality score.
The score is a simple, honest heuristic, not a full data-governance audit: it weighs how complete your data is most heavily, then docks smaller amounts for duplicate rows and columns that never actually change value. Treat it as a quick first read, not a certified report.
What happens to my file?
Nothing is kept. It's read once to compute the stats above and never stored afterward — same handling as DashPrompts' own dashboard generator.
Questions
Is this free?
Yes, completely free, no account or signup needed.
What file types work?
CSV, XLS, XLSX, or XLSM, up to 4 MB.
What does the quality score actually measure?
Mostly how complete your data is (few blanks), with smaller deductions for duplicate rows and columns that never change value. It's a quick, honest heuristic, not a certified data-quality audit.
Is my data stored anywhere?
No. It's read once to compute the stats shown and never retained afterward.
