Google Docs

google_docs is a wrapper around google-api-ruby-client. It allows you to get information about the spreadsheet and format it. Currently, gem consists of two classes GoogleDocs::SpreadSheet and GoogleDocs::Sheet and uses Sheets API V4.

Main features:

Set up columns width
Update grid properties of the sheet (freeze columns/rows)
Update and format cells
Merge/unmerge cells in the given range
Export google sheet documents as PDF
Read information from certain sheet

Pre requirement

In order to use our gem your application should have configured Google OmniAuth already. Also you should configure Google Sheet API

Installation

You can add it to your Gemfile with:

gem 'google_docs'

Then run bundle install

Getting started

Initialize new object of GoogleDocs::SpreadSheet class

spreadsheet = GoogleDocs::SpreadSheet.new('some_google_access_token', 'some_spreadsheet_id')

After successfull intialization we can call the following methods:

spreadsheet.properties returns properties of the spreadsheet
spreadsheet.sheets get all sheets of the spreadsheet.

If you want to get sheet directly by key:

sheet = GoogleDocs::Sheet.new(spreadsheet_id: required, sheet_id: required, google_access_token: required)

By default, after object initialization there are no modification request to be executed. You should prepare requests and only then call sheet.apply_changes! to send requests. To add requests you can run following methods:

sheet.setup_columns_width(data) - build request to set up columns width. Argument data should have the following format:
```
{
  'A'  => integer,
  'D'  => integer,
  ...
}
```
The keys of hash are the columns letters and values of hash - width in pixels for these names in sheet respectively. For instance, suppose, you have the following sheet: and our data are the following:
```
{
  'A' => 50,
  'B' => 150,
  'C' => 150,
  'D' => 100,
  'E' => 50,
  'F' => 100,
  'G' => 700
}
```
After our method have been executed we receive:

sheet.update_grid_properties(props) - build request to update properties of the sheet, i.e. to freeze rows and columns while user is scrolling document. Argument props must have the following format:

{
    row_count:           integer,
    column_count:        integer,
    frozen_row_count:    integer,
    frozen_column_count: integer,
    hide_gridlines:      boolean
}

For instance, suppose, you have the following data:

props = {
  row_count:           7,
  column_count:        7,
  frozen_row_count:    2,
  frozen_column_count: 1,
  hide_gridlines:      true
}

After our method have been executed we receive:

sheet.update_cells(data) - build request to update all cells in a range with new data. Argument data is an array with rows. Each row is an array of cells. Cell can be a String, Number, Boolean or Hash. When the value of cell starts from '=' it will be sent as formula. When cell is a Hash it can contain additional formatting options. Schema of the data attribute:

[
    [
        {
            value: 'any cell value'
            borders: {
              left, right, top, bottom: {
                style: :dotted, :dashed, :solid, :double
                width: 1..3
                color: '#RRGGBB'
              }
            }
            background_color:       '#RRGGBB'
            horizontal_alignment:   :left, :center, :right
            vertical_alignment:     :top, :middle, :bottom
            hyperlink_display_type: :linked, :plain_text
            wrap_strategy:          :overflow_cell, :legacy_wrap, :clip, :wrap
            text_direction:         :left_to_right, :right_to_left
            number_format: {
              type:    :text, :number, :percent, :currency, :date, :time, :datetime, :scientific
              pattern: "#,##0.0000"
            }
            text_format: {
              foreground_color: '#RRGGBB'
              font_family:      'Terminus'
              font_size:        integer
              bold:             boolean
              italic:           boolean
              strikethrough:    boolean
              underline:        boolean
            }
        },
        'string cell',
        number_cell
    ],
    # new row
    [ {cell 1}, {cell 2}, ... {cell n} ]
]

For instance, data could look like:

data = [
  [{ value: 'books', background_color: '#f1c232', text_format: { bold: true }, horizontal_alignment: :left,
     borders: { bottom: { style: :solid, width: 3, color: '#RRGGBB' },
                right: { style: :solid, width: 3, color: '#RRGGBB' } } }
  ],
  [
    { value: 'id',           background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :right },
    { value: 'author',       background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 'title',        background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 'genre',        background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 'price',        background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 'publish_date', background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 'description',  background_color: '#b7b7b7', text_format: { bold: true }, horizontal_alignment: :center }
  ],
  [

    { value: 'Gambardella, Matthew', text_format: { italic: true }, horizontal_alignment: :center },
    { value: "XML Developer's Guide", text_format: { underline: true }, number_format: { type: :text }, horizontal_alignment: :center },
    { value: 'Computer', text_format: { bold: true }, horizontal_alignment: :center },
    { value: 44.95, number_format: { type: :currency }, text_format: { strikethrough: true, foreground_color: '#FF0000' }, horizontal_alignment: :center },
    { value: '10/01/2000', number_format: { type: :date}, horizontal_alignment: :center },
    { value: 'An in-depth look at creating applications', text_format: { font_family: 'Courier New' }, horizontal_alignment: :left },
  ],

    { value: '16/12/2000', number_format: { type: :date}, horizontal_alignment: :center },
    { value: 'A former architect battles corporate zombies, an evil sorceress', text_format: { font_family: 'Courier New' }, horizontal_alignment: :left },
  ]
]

After our method have been executed we receive:

sheet.merge_cells(props) - build request to merge cells in the given range. Index count starts from 0. Argument props has the following format:

{
    type: :merge_all, :merge_columns, :merge_rows
    range: {
      start_row_index:    integer,
      end_row_index:      integer,
      start_column_index: integer,
      end_column_index:   integer
    }
}

For instance,

props = {
  type: :merge_rows,
  range: {
    start_row_index:    0,
    end_row_index:      1,
    start_column_index: 0,
    end_column_index:   7
  }
}

After our method have been executed we receive:

sheet.unmerge_cells(range) - build request to unmerge cells in the given range, where argument range has the following format:

    start_row_index:    integer,
    end_row_index:      integer,
    start_column_index: integer,
    end_column_index:   integer
}

sheet.apply_changes! - execute all reguests.

sheet.get_rows_values - read information from each row in the sheet. Output example:

[
  ["books"],
  ["id", "author", "title", "genre", "price", "publish_date", "description"],
