Extract rows with the highest or lowest N values in a numeric column
Extract the top N or bottom N rows from a CSV ranked by a numeric column.
🛡️ Your rows never leave your browser.
Why Onfyt: Adds an optional '_rank' column and supports percentage-based extraction (top 10%) in addition to fixed N—matching the percentile use case in sales territory analysis.

How this tool works
Finding top performers is a standard analytical operation: top 10 customers by lifetime value, worst 5 products by return rate, top 20% of leads by score. SQL's ORDER BY + LIMIT handles this in databases, but analysts working with exported CSV files need the same capability without a database.
DataFix sorts by the selected column, extracts the top N rows, and optionally adds a rank column. Percentage mode extracts the top X% of rows rather than a fixed count.
Extracting the highest-frequency or largest numeric values in a column isolates top-performing products, frequent error codes, or key transaction segments for targeted analysis.
Extracting the most frequent or highest-value records in a dataset isolates top-performing SKUs, primary error codes, or VIP customer tiers. Our ranking engine computes frequencies and relative distribution percentages with rapid streaming calculation.
Top-N filtering enables rapid Pareto analysis (the 80/20 rule), highlighting dominant transaction tiers, recurring server exceptions, and top customer cohorts with instantaneous visual sorting and aggregate contribution ratios.
Isolating the most frequent values in a column pinpoints leading sales channels, dominant error codes, and top customer tiers. Calculating relative frequency percentages provides immediate insight into categorical distributions. Threshold cutoff controls allow grouping minor tail values into a consolidated 'Other' bucket, producing clean distribution summaries for charts and executive presentations. Automated frequency bar indicators illustrate relative category dominance directly within the preview table.
Things that usually go wrong
- Ties at the Nth position are all included — you may get slightly more than N rows.
- Non-numeric values are excluded from ranking.
Edge cases we tested
🧪 Tied values at the cutoff (two rows both with the Nth-highest value)
Both included; output may have N+1 rows when there's a tie.
🧪 Revenue column stored as text ('$4,500')
Numeric coercion applied after stripping currency symbols.
Frequently Asked Questions
Are ties included?
Yes — all rows that share the Nth rank value are included.
Can I get the bottom N instead?
Yes — toggle 'Bottom N' for the lowest values.
