  1. Click Get Data to access the Quandl Formula Builder dialog box.
  2. Database: Select the database you would like to download from or search with a database code. (For instance, the database code for Mergent Global Fundamentals is "MF1".)
  3. Data: Choose the table you would like to download.
  4. Columns: Select the columns you wish to include (by default, all columns will be downloaded).
  5. Filter: The dialog box will provide the relevant filters dynamically.
  6. Placement: Select the cell where you would like to place the data.

Download table data with the Quandl QTABLE formula

In addition to the Quandl Formula Builder, the Quandl Excel add-in allows users to download tables data with the QTABLE formula. Users can directly type a formula into a cell to download data.

The structure of the formula is given below. Note that you can have multiple filters as part of a single query.

=QTABLE(Datatable code, columns, filter name, filter value, filter name, filter value)

DESCRIPTION

Datatable code (required)

DATATABLE CODE
Table codes can be found on each database page on our website.


Example: The table code for Zacks Fundamentals Condensed (“ZACKS/FC”) can be found on quandl.com/databases/ZFA.

Filter columns (optional)

COLUMN NAME
You can specify the column you wish to query here. If a column is not specified, all columns from the table will be retrieved.


{“COLUMN NAME”, “COLUMN NAME”}


To specify multiple columns, use curly brackets “{}” and indicate the columns you wish to query in quotation marks. Users are encouraged to directly reference cells that contain the column names.


See the Reference cells in the Quandl formula section below for details.


Examples:
comp_name retrieves only the data found in the column comp_name.


A1:E1 retrieves the columns specified by these referenced cells.

Filter rows (optional)

By specifying one or more columns to act as the filter name, you can download your desired rows. If the value in a given column matches the specified filter value, the row containing that value is returned.


Only columns designed as “filterable” in the database’s documentation page can be used as criteria to filter rows.


Example: “ticker”, “per_type”, “per_end_date” are possible filters for the ZACKS/FC table.

Reference Cells in the Quandl Formula

Users are encouraged to directly reference cells that contain the desired specification when using the Quandl formula. The following two examples are meant to get you familiar with referencing cells in the Quandl Formula.

Example 1: Query multiple columns in tables

This example queries and downloads four columns from the ZACKS/FC tables. Enter the Datatable Code and column names you wish to query in the worksheet (e.g., A1, A2, A3, A4 cells). Use the QTABLE formula and reference these cells (e.g., A1:A4).

Example 2: Query multiple columns with filters in tables

This example queries and downloads four columns, filtering for only the AAPL value in the ticker column and for the Q value in the per type column. To do this, enter the Datatable Code and column names you wish to query in the worksheet (e.g., A1, A2, A3, A4 cells). Then enter the filter names and filter values you wish to filter by. Use the QTABLE formula and reference these cells.
