How is the data formatted? ISO 8601 dates  i hope.....
(ISO date=  YYYYMMDDTHHMM  optionaly added seconds and more smaller fractions...)

#!/bin/bash

isodate=$( grep 'expiration:' info.txt | sed -s 's/expiration://' )
edate=${isodate%T*}
expdate=$( date +%4Y%m%d --date='+ 10 days' )
if [ "$expdate" -eq "$edate" ]
then
        echo "done" >done.txt
fi

Then it can be:
#!/bin/bash

isodate=$( grep 'expiration:' info.txt | sed -s 's/expiration://' )
edate=${isodate%T*}
expdate=$( date +%4Y-%m-%d --date='+ 10 days' )
if [ "$expdate" -eq "$edate" ]
then
        echo "done" >done.txt
fi
