Metadata Text Files
^^^^^^^^^^^^^^^^^^^
Unless :option:`--no-captions` is given, Instaloader creates a ``.txt`` file
along with each post where the Post's caption is saved.
You can customize what metadata to save for each Post or StoryItem with
:option:`--post-metadata-txt` and :option:`--storyitem-metadata-txt`. The
default is ``--post-metadata-txt={caption}`` and no storyitem metadata txt.
These strings are formatted similar as in the :ref:`filename-specification` and
the result is saved in text files, unless it is empty.
Specifying these options multiple times results in output having multiple lines,
in the order they were given to Instaloader.
The field names are evaluated to :class:`Post` or :class:`StoryItem` attributes,
and as such, the same fields are supported as in :ref:`filename-specification`
and :ref:`filter-posts`.
For example, to save the current number of likes for each post, rather than
the post's caption::
instaloader --post-metadata-txt="{likes} likes." <target>
Note that with this feature, it is possible to easily and fastly extract
additional metadata of already-downloaded posts, by reimporting their JSON
files. Say, you now also want to export the number of comments the Posts had
when they were downloaded::
instaloader --post-metadata-txt="{likes} likes, {comments} comments." <target>/*.json.xz
