Delimited Data Sampler

Keep the header and sample without replacement. Interval uses floor(i*n/k); edges gives the extra row to the beginning; seeded random uses FNV-1a with Mulberry32 and Fisher–Yates, then original order. This deterministic PRNG is not cryptographic and may differ from the source sequence. 32 KiB / 999 records / 10,000 cells.

Inputs and settings

Processed in this tab without uploading or storing inputs. Each text field is limited to 32 KiB and complete output to 1 MiB; additional format and model limits apply.

Results

Review the settings and run. Editing inputs clears old results.

Processing model and limits

How to use this tool

Load the example, confirm field units and processing rules, then run locally. Editing any input clears the old result. Copy or download the complete output explicitly.
