How to create a sample dataset from a large csv
- Step 1Identify the row count you need for testing — Decide how many rows represent a realistic sample — typically 1,000 to 5,000 for most pipelines.
- Step 2Drop the large CSV into Row Limiter — The tool reads the file locally without uploading it.
- Step 3Enter the row count and apply — Type the number of rows to keep and run the limit.
- Step 4Download the sample file — Use the smaller CSV for your prototype, dashboard, or ETL test run.
