Error Levenshtein Distance to Excel Writer

I created the Levenshtein Distance with “String Distance” and created an extra column with “Distance Matrix Calculate”.

This has the format “Distance vector”.

Now I would like to create an Excel file with the Excel Writer. Unfortunately it does not work. What is the problem?

Can I change the column format “Distance vector” to “String”, or is there another way to create an Excel file?

Many thanks and BR
