• The following replacements happen:

    string.replace("' '",' ')
    string.replace('\\n','\n')
    string.replace('\\r','\r')
    string.replace('\\t','\t')
    string.replace('COMMA',',')
  

• Saleae Logic will export hex values as strings (e.g., '1' for 0x01) so keep this in mind if you find such items.
