The active query defines the file, not how far you scrolled. Filter, time range, ordering, and dataset are what get exported, so the same query exported twice gives you the same records. For spans and web events that includes a focused duration range picked on the heatmap, because that selection is part of what the table is querying.
Exports include up to 5,000 records. Beyond the cap, use the Dash0 CLI. The menu builds the command for your current query, ready to copy.
