saveResponseBodyAsAttachment without table name/sys_id

[Appli]

Hi, I would like to retrieve Excel file from external source, save it as attachment in sys_attachment table, process and delete it finally.

Or just retrieve it, save in memory, and process. Closest guidelines I found - here

A challenge - saving an attachment requires adding target table (like incident) and sys_id (like its incident record):

request.saveResponseBodyAsAttachment(tablename, recordSysId, filename);

However my application does not interact with any table in SN, hence the method above does not work to me. Attaching to the script itself does not look to be a nice solution either. Any workaround?

Thank you in advance.

The GlideExcelParser API can parse Excel spreadsheets in code, using an input stream to an attachment accessed via its sys ID using the GlideSysAttachment API.

You can create sys_data_source records on the fly -- or reuse the same record -- and attach the spreadsheet as an attachment to that record, deleting the attachment when your code is done processing the spreadsheet.
