You have to do it in your analysis, with preparation step of type filter, for instance:
- keep rows on numerical range.
- keep only rows with this value.
and for more complex filter, like substring, you could use "Extract with regular expression", check "create special found column" and then keep only rows with "true"...
Next, if your preparation script is deployed (in the flow), you build it and download the output.
Otherwise, you can click Actions / "Download processed data".
