Transparent methodology
What the result includes—and what it does not
Built for people extracting a subset: one city, one status, everything above a threshold.
Calculation method
- 1Rows stream through one condition on a chosen column: contains, equals, starts/ends with, numeric greater/less than, or emptiness checks.
- 2Numeric comparisons apply when both sides parse as numbers, so '100' correctly beats '99'.
Assumptions and limits
- One condition per pass in V1 — chain runs for AND logic (the result feeds the next filter without re-uploading).
- File contents are processed locally and never uploaded; the only telemetry is an aggregate operation counter with no file names, column names or contents.
