How to use CSV Nonoverlapping Interval Lookup

Classify source observations against your own nonoverlapping bands without interpolating or inventing values. Exact bounded decimal comparisons distinguish touching open/closed endpoints, and unmatched points follow your chosen policy.

  1. Enter input, interval csv, one point column json, one lower-bound column json, one upper-bound column json.
  2. Choose the settings for csv nonoverlapping interval lookup, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 100,000 characters and 5000 records per table. Strict finite decimals with exact magnitude≤1e15 and bounded 500-place representation.
  • Intervals are sorted locally and must have positive width with no overlap under the selected closure. No dates, timezone inference, periodic ranges or automatic professional threshold recommendations.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Can adjacent closed bands both own the same endpoint?

No. Under [] the touching endpoint would belong to both bands, so the interval table is refused as overlapping.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
