Crunch the numbers in the browser.
Run real statistics on a CSV without a spreadsheet or notebook — each tool runs locally and shows its work. For a reusable quality contract, start with CSV Profiler; for a narrative report, see CSV data analysis.
Measure what's in the data.
Correlations, outliers, percentiles, moving averages, time resampling and A/B significance.
Profile and validate.
Profile observed signals, test reusable quality contracts, inspect calculated columns, and validate CSV structure.
Ask questions, then visualize.
Run SQL against the CSV, or hand it to the dashboard for a full auto-analysis.

Common questions.
-
·
Do these run on a server?
No — every statistic is computed in your browser. Nothing is uploaded; verify in DevTools → Network.

·
How big a file can they handle?
Large files are parsed off the main thread, so hundreds of thousands of rows work on a modern machine. Past that, it depends on your memory.

What's the difference between this and the dashboard?
These are focused single-purpose tools (one statistic each); the Dashboard Builder runs a broad automatic analysis and renders charts.
