It sounds as though you might have only had one row selected in the spreadsheet view. Please click the 'Select' icon as shown in the image below to highlight all rows and then either copy and paste the data into a spreadsheet application or save to file.
If you save the data to a text file, you should be able to read it in to a database application. You can also set the data file type to be a text file or comma separated values (.csv) file in the main PLW Recorder window when you create the data file to record to.
I hope this helps.
