This inputs the scan results from ``sample.json``, runs the post-scan plugin ``--classify`` and
outputs the results for this scan to ``sample_2.json``.

You can also convert the input ``.json`` file to other output format
without using any scan option.

For instance,::

scancode --from-json sample.json --yaml sample.yml

The above command takes ``sample.json`` as input and generates file in ``.yml`` formats.

.. note::

This only works for options that require only the input JSON file;

Generally the post-scan options (like --summary, --todo) are configured to just operate on the codebase (with top-level licenses/packages etc and all resource level results) and this should work fine with --from-json
The core scan options (like --license --info) and pre-scan options cannot be run here. There are some post-scan options which have required options as dependencies, so those also need to be there in the loaded scan if those options are being specified.

@AyanSinhaMahapatra I am wondering is it true that all the "Pre-Scan" options cannot be run with --from-json?
https://scancode-toolkit.readthedocs.io/en/latest/cli-reference/list-options.html#all-pre-scan-options
It seems to be the "--ignore" and "--include" don't really need the code files to have it work (I didn't look at the source code to verify it). Also, https://scancode-toolkit.readthedocs.io/en/latest/cli-reference/core-options.html#from-json-option , the current --from-json` is usung --classify`` as a sample.

For the post-scans, I want to verify that if an option's dependencies are missing, the command still executes without errors, it just won’t return results related to the missing dependencies, correct?

options that rely on other files or source code will not work.

I'm not sure we want to remove these sections, they are pretty useful IMHO

@AyanSinhaMahapatra I'm removing this from the list-options since extract.rst is already included in other-commands.rst. Having it in both places seem redundant.
