.. _auto_curves_import_csv:

*IMPORT CURVES FROM CSV STRING*
===============================

Parses a raw CSV string into one or more curve objects, using the `ENDCURVE` delimiter to separate multiple curves within a single input. Use this worker whenever curve data arrives as inline text (e.g., from a upstream worker or a manual paste) rather than as a file on disk.
