If by 'spreadsheet" you are using the standard Numbers technology to mean document then the answer is no, there is no way to automatically move data from one document to another, only a semi-automatic way involving a script.
If by 'spreadsheet' you mean table, then there are ways to move data from one table to another within the same document even if the tables are in different sheets in the document.
However, having more information about your use case and the structure of your documents and the tables within them would help.
