i'd highly recommend to use dataset's GUID in the file name. For an example you can see how qcodes' dataset export feature is implemented see here https://microsoft.github.io/Qcodes/examples/DataSet/Exporting-data-to-other-file-formats.html


path, _fltr = QtWidgets.QFileDialog.getSaveFileName(
self,
'Export to .csv file',
default_name,
'comma separated files (*.csv);;all files (*.*)',
)

if path:
LOGGER.info(f"Opening: {path}")
ds = load_dataset_from(self.filepath, runId)
df = ds.to_pandas_dataframe()
df.to_csv(path)
