The below error appears to arise whenever I try to edit the table cell 'Column Names'. Any ideas for a resolution?
AutoCAD Error During Data Extraction: 'Unhandled Exception... Value cannot be null. (Parameter 'stream')
Hi @Jake_PCH
Are you trying to edit the column headers, or ‘NO.’ and ‘TEXT’ circled red?
If you are, then understand you can’t edit on page 5 because that page is in the middle of the Data Extraction procedure.
You must completes all ‘pages’ of your data extraction. If your extracted output is a Table such as .xls, then edit the table. The data extraction wizard won’t let you edit on page 5.

@pendean Thanks for the suggestion.
@ChicagoLooper This does not appear to be the case - at least not in ACAD 2025. I have edited the column headers in previous extractions without problem, using the 'Rename Column' dropdown within the Data Extraction Wizard.
