How do I save my lab data to a file?

How do I save my lab data to a file？ In Measurement & Automation Explorer, I have connected NI devices and obtained experimental data through 'NI-DAQm Task' measurements, how do I save the data? By using the export options in the top right corner of the figure, option 1 is to copy to pasteboard, but the data format is not correct; option 2 is to export data to Excel, but I can't find the path where the file is located; option 3 is to export data to DIAdem, but the exported data is not the same as the data in the software? Is there a more efficient and convenient way to save the data? Or where should I look for the file exported through optin 2? I tried the path where the software is located and did not find the file.
