How to use Consecutive CSV Run Segmenter

Inspect contiguous status or category stretches without grouping distant records together. Every run reports its key tuple, length, and source record interval, so separated appearances of the same value remain separate evidence.

  1. Enter input, run-key column names json.
  2. Choose the settings for consecutive csv run segmenter, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 200,000 CSV characters,5000 records and 100 declared key columns.
  • Exact string tuples and physical record order only. No sorting, numeric thresholding or duration inference; CSV record numbers count parsed records, not physical lines within quoted cells.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Are two open stretches merged if a closed row separates them?

No. A run requires adjacency. The later open stretch receives a separate start/end interval.

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.
