JASON error in redirects.json file

When I try to upload my redirects.json file I get the following error:
Could not parse JSON: Unexpected token : in JSON at position 3

Begining of file looks like this:

301:
/untitled-13: /best-3-dog-foods-for-shedding-3-will-shock-you
/untitled-16: /ingredient-by-any-other-name

Can you try renaming redirects.json to redirects.yaml? Also make sure the file contents look like this:

301:
  /untitled-13: /best-3-dog-foods-for-shedding-3-will-shock-you
  /untitled-16: /ingredient-by-any-other-name

Thank you that worked.
