Spreadsheet -> OPML Generator

19 | 20 |

An OPML describes a set of RSS feeds, and is a nice way of sharing a 21 | set of feeds with the world. You can use this app to generate an OPML 22 | based on a public Google Spreadsheet. 23 |

    24 |
  1. Create a spreadsheet with columns "title" and "url". 25 |
  2. Publish the spreadsheet by clicking "Share" -> "Publish as a webpage" 26 | -> "Start publishing." Set it to auto-publish on save if you want. 27 |
  3. Enter the URL of the spreadsheet below:
    28 | 29 |
  4. Enter a title for the OPML (optional):
    30 | 31 |
  5. Your OPML should now be generated at this URL:
    32 | 33 |
  6. Now you can share that URL with others and they can do exciting 34 | things like 35 | import it into Google Reader. 36 |
37 |

For an example, see this published spreadsheet 38 | and the resulting OPML. 39 |

Note: This is not a production-level service, 41 | it it just a tool I put together for use on my 42 | recipe blogs portal. 43 | You can deploy your own version of this or modify it for your needs 44 | by grabbing the source code from github. 45 |
