sheetsite: sheets for sites

Keep a website or directory in sync with a google sheet.

Features:

• Copy a google spreadsheet locally, as json or excel format.
• Can strip specified tabs, columns, or cells from the spreadsheet, in case not all of it should be copied along.
• Can push a filtered json copy out to a git repository, handy for maintaining a website based on a private shared spreadsheet.
• Can augment the sheet with geocoding, adding latitude and longitude based on address fields for example.
• Can notify people by email with a summary of updates.

Installation

For the basics:

pip install sheetsite

For all bells and whistles, when automating a sheet-to-site workflow:

pip install sheetsite[queue]

Specifying the source and destination

The sheetsite utility, when run without any arguments, will expect to find all necessary options in a _sheetsite.yml file. A simple example of such a file is:

source:
  name: google-sheets
  key: 15Vs_VGpupeGkljceEow7q1ig447FJIxqNS1Dd0dZpFc
  credential_file: service.json

destination:
  file: sheet.xlsx

The file should have two stanzas, source specifying where to get data from, and destination specifying where to put it. This examples reads a private google spreadsheet and saves it as sheet.xlsx. The key comes from the url of the spreadsheet. The credentials file is something you get from google.

Here's an example that outputs json:

source:
  name: google-sheets
  key: 15Vs_VGpupeGkljceEow7q1ig447FJIxqNS1Dd0dZpFc
  credential_file: service.json

destination:
  file: _data/directory.json

You could now build a static website from that .json, see http://jekyllrb.com/docs/datafiles/ for how, or see an example at https://github.com/datacommons/commoners

Here's an example that adds some geocoded fields and directly updates a git repository:

source:
  name: google-sheets
  key: 19UaXhqPQ0QHEfSWS_adDEtPwYstq8llK2YijpvFZcKA
  credential_file: service.json

flags:
  add:
    directory:
      - LAT
      - LNG
      - COUNTRY
      - STREET
      - REGION
      - LOCALITY

destination:
  name: git
  repo: git@github.com:datacommons/commoners
  file: _data/directory.json

Strip private sheets, columns, or cells

By default, sheetsite will strip:

• Any columns whose name is in parentheses, e.g. (Private Notes)
• Any cells or text within cells surrounded by double parentheses, e.g. ((private@email.address))
• Any sheets whose name is in double parentheses, e.g. ((secret sheet))

Geocoding

If you have a table with a column called address, sheetsite can geocode it for you and pass along the results. Just add the following in your yaml:

flags:
  add:
    table_name_goes_here:
      - latitude
      - longitude
      - country
      - state
      - city
      - street
      - zip

You can add just the columns you want. Geocoding results are cached in a _cache directory by default so they do not need to be repeated in future calls to sheetsite.

The full list of columns (with synonyms) available is:

• latitude / lat
• longitude / lng
• latlng
• country
• state / province / region
• city / locality
• street
• zip / postal_code

Normally you won't actually have a stand-alone address column. More usually, information will be spread over multiple columns, or some will be implicit (e.g. the state/province and country). You can tell sheetsite how to construct addresses for geocoding by listing columns and constants to build it from. For example:

flags:
  address:
    table_name_goes_here:
      - street_address1
      - street_address2
      - city
      - Manitoba
      - Canada
  add:
    table_name_goes_here:
      - postal_code

This tells sheetsite to produce addresses of the form:

<street_address1> <street_address2> <city> Manitoba Canada

And add a postal_code column populated by geocoding.

It is possible to request columns directly in the spreadsheet. Just wrap the column name in square brackets, like [state] or [zip]. Any blank cells in such columns will be filled using geocoding based on the address given in that row. If the address columns have not been configured in flags then the address must be present in a single column literally called address.

Row uuids

There's a random feature to add uuids to rows. Just add a column called dccid for some reason:

flags:
  add:
    table_name_goes_here:
      - dccid

A uuid will be added to each row. A good faith effort will be made to keep that uuid constant across updates, keeping it linked to the row where it first appeared.

Grouping locations

If there are several rows of a sheet that will give locations that should be thought of as a single unit (e.g. an organization with multiple locations), you can tell sheetsite about that. To do so, give it a group key. Every row for which the group is the same (and not blank) will be bound together. When geocaching, blank cells in address cells will be filled in with information from the first row in this group. For example, with this configuration:

flags:
  group: WEBSITE

Then for a table like the following:

STREET,   CITY,   STATE,    WEBSITE
...
17 N St,  Foo,    Utopia,   joe.ut
16 S St,  ,       ,         joe.ut
...

During geocoding, 16 S St would be assumed to be in Foo, Utopia.

Renaming columns

Columns can be renamed. This will occur before any other operation.

flags:
  rename:
    table_name:
      old_column_name1: new_column_name1
      old_column_name2: new_column_name2

Getting credentials

Obtain credentials for accessing sheets from the Google Developers Console.

Make sure you share the sheet with the email address in the credentials file. Read-only permission is fine.

Examples

For example, the map at http://datacommons.coop/tap/ is a visualization of data pulled from a google spreadsheet, styled using https://github.com/datacommons/tap via github pages.

sheetwatch

It can be useful to automate and forget sheetsite, so that updates to a google spreadsheet propagate automatically to their final destination. The sheetwatch utility does this. It requires a queue server to operate. To install, do:

pip install sheetsite[queue]

Install any queue server supported by celery. For example, redis:

sudo apt-get install redis-server
redis-server

We need to set some environment variables to let sheetwatch know where to find the queue server:

export SHEETSITE_BROKER_URL=redis://localhost
export SHEETSITE_RESULT_BACKEND=redis://localhost

The sheetwatch program needs a cache directory for its operations.

export SHEETSITE_CACHE=$HOME/cache/sites

Finally, it needs to know where there is a directory full of yml files describing any sheets to monitor and their corresponding sites:

export SHEETSITE_LAYOUT=$PWD/sites/enabled

We now start a worker:

sheetwatch worker

The last thing we need to do is check a mailbox from time to time for sheet change notifications from Google, and kick off site updates as needed:

  export GMAIL_USERNAME=*****
  export GMAIL_PASSWORD=*****
sheetwatch ping --delay 60
