Mail merge without .ODB file

Each time a use a new data origin from a Calc file, Writer create a new .ODB file in my documents folder. Does anyone know how to avoid this behavior?

Hi @Andres1, What version of LibreOffice are you using, and on what OS? We can try to replicate the creation of the .ODB file.

I’ve just follow the tutorial but it also create a new .ODB file in my documents folder. Thank you anyway.

I believe you cannot avoid the ODB file, because it is the only way LibreOffice has to contains a data source (independently if the source is a local spreadsheet or a corporate database connection.
