Issue with get_sheet_as_excel() – KeyError: 'content-disposition'

I am using Python smartsheet sdk to connect to smartsheet. The line

smartsheet_client.Sheets.get_sheet_as_excel(sheet_id, folder_path)

was working fine until yesterday. Now it's failing with KeyError: 'content-disposition'. No changes were made to the code or permissions. Please advise on how to resolve this.

Thanks,

Liam

If the sheet was deleted, moved to another workspace, or you lost access, the API might not return a proper file stream (and instead return an error response — but your code still tries to parse it as a file).

Hi Naeem,

I am also facing the same issue since 06/27/25. No changes to the workspace or the access. Could you please advise if there was been any upgrade to the Smartsheet?

Hey everyone,

I ran into this issue today with get_sheet_as_csv() and was able to resolve by updating smartsheet's python SDK to the most recent version:

pip install smartsheet-python-sdk==3.0.5

Also just found out that for me the get_sheet_as_csv method slightly changed:

Before this would save as a CSV using the sheet name as the filename (on version 2.105.1):

smart = smartsheet.Smartsheet()
smart.Sheets.get_sheet_as_csv(SHEET_ID, os.path.dirname(os.path.realpath(file)))

Now to get the same behavior, I do this (on version 3.0.5)

smart = smartsheet.Smartsheet()
csv_file = smart.Sheets.get_sheet_as_csv(SHEET_ID, os.path.dirname(os.path.realpath(file)), CSV_FILENAME)
csv_file.save_to_file()

The documentation shows that:

smartsheet package — Smartsheet Python SDK 3.0.5 documentation

get_sheet_as_csv(sheet_id, download_path, alternate_file_name=None)

Get the specified Sheet as a CSV file.

Parameters:

sheet_id (int) – Sheet ID
download_path (str) – Directory path on local machine to save file.
alternate_file_name (str) – Filename to use instead of name suggested by Content-Disposition.

Returns:

DownloadedFile
