https://community.esri.com/t5/arcgis-api-for-python-ideas/option-to-allow-null-values-when-using-to/idi-p/1374169 <P>The title says is all. I'd appreciate being able to maintain null values when converting a SeDF to a featureclass in a gdb. I've used pandas.fillna() with fillers like a space before, but sometimes a null value is there for a reason, and I'd prefer to leave it null.</P> Wed, 24 Jan 2024 22:01:47 GMT KellyTaylor 2024-01-24T22:01:47Z https://community.esri.com/t5/arcgis-api-for-python-ideas/option-to-allow-null-values-when-using-to/idi-p/1374169 <P>The title says is all.
