Can a row in a spread sheet of LibreOffice be updated or created via an E mail attachment. Like the Power automate in excel.

Is there a way to update my sheet in Libre like below with excel ?

The LO has not built-in E-mail client, but you can control the third party Thunderbird email client by your StarBasic+API macro code.

(I controlled the Thunderbird for sending e-mails and attachments only. I never tried to manage the attachments received by the Thunderbird.)
