```

sqlite-utils convert parsedatetime mydb.db mytable mycolumn
sqlite-utils convert parsedate mydb.db mytable mycolumn
sqlite-utils convert lambda mydb.db mytable mycolumn --code='str(value).upper()'

I like the idea that `lambda` is the default action, but in this form it's required that the second argument (the word after `convert`) be the name of the recipe that is being applied to avoid any potential confusion with the database filename.

An ugly solution would be to make all four of those options available on `sqlite-utils convert` - and return an error if you try and use one of those without specifying the accompanying recipe.
