Using the following code I could get rid of the brackets and alphabetic characters but not able to get rid of single quote marks

Tried strrep and regexprep but it doesn't work

The single quotes are for presentation purposes and are not part of the stored value.

The extract that you show us contains only digits in those columns. You could replace the variable by str2double() of the variable if numeric is appropriate for the column.

If numeric is not suitable then you could get rid of the apostrophes for presentation purposes by converting the variable to categorical

Yes it worked. Thank you
