With recent Anki versions, there is no need to export+import. An example is provided in this forum post.
Sometimes you may create a deck, or download a shared deck, with several things in one field, such as text and audio, but then later decide that you would rather have the information in two fields so that you can have more precise control over what displays on each card. One option is to add a new field and then manually cut and paste the content between fields; this may be the fastest if you have less than a hundred cards or so, but otherwise it will be very tedious and slow. Here is a method you can use based on exporting to a text file and doing a search and replace; as an example, we'll focus on
s/\[sound/\t\[sound/. Otherwise, if you're not sure how to form the expression, you can ask on the Community section or look for regular expression help on the Internet.If you run into problems, please ask on the Community category, as this is outside the scope of the official support we can provide for Anki.
