Connect to Typeform Data in Google Apps Script via Connect AI
Google Apps Script empowers users to build custom functionality within their Google documents, including Google Sheets and Google Docs. Apps Script natively supports SQL Server connectivity via JDBC, providing a powerful extensibility tool for connecting Google cloud applications to external data. Paired with the SQL connectivity offered by CData Connect AI, users can easily access live Typeform data directly from within their Google documents.
This article shows how to connect to Typeform in Connect AI and provides sample scripting for processing Typeform data in a Google Spreadsheet.
Configure Typeform Connectivity for Google Apps Scripts
Connectivity to Typeform from Google Apps Scripts is made possible through CData Connect AI. To work with Typeform data from Google Apps Scripts, we start by creating and configuring a Typeform connection.
CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "Typeform" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Typeform.
Start by setting the Profile connection property to the location of the TypeForm Profile on disk (e.g. C:\profiles\TypeForm.apip). Next, set the ProfileSettings connection property to the connection string for TypeForm (see below).
TypeForm API Profile Settings
Authentication to TypeForm uses the OAuth standard.
To authenticate to TypeForm, you must first register and configure an OAuth application with TypeForm here: https://admin.typeform.com/account#/section/tokens. Your app will be assigned a client ID and a client secret which can be set in the connection string. More information on setting up an OAuth application can be found at https://developer.typeform.com/get-started/.
Note that there are several different use scenarios which all require different redirect URIs:
- CData Desktop Applications: CData desktop applications (Sync, API Server, ArcESB) accept OAuth tokens at /src/oauthCallback.rst. The host and port is the same as the default port used by the application. For example, if you use http://localhost:8019/ to access CData Sync then the redirect URI will be http://localhost:8019/src/oauthCallback.rst.
- CData Cloud Applications: CData cloud applications are similar to their desktop counterparts. If you access Connect AI at https://1.2.3.4/ then you should use the redirect https://1.2.3.4/src/oauthCallback.rst.
- Desktop Application: When using a desktop application, the URI https://localhost:33333 is recommended.
- Web Application: When developing a web application using the driver, use your own URI here such as https://my-website.com/oauth.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the Client Id that is specified in your app settings.
- OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
- Click Save & Test
-
Navigate to the Permissions tab in the Add Typeform Connection page and update the User-based permissions.
Add a Personal Access Token
When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Typeform data from Google Apps Script.
Connect to Typeform Data from Apps Script
At this point, you should have configured a connection Typeform in Connect AI. All that is left new is to use Google Apps Script to access Connect AI and work with your Typeform data in Google Sheets.
In this section, you will create a script (with a menu option to call the script) to populate a spreadsheet with Typeform data. We have created a sample script and explained the different parts. You can view the raw script at the and of the article.
1. Create an Empty Script
To create a script for your Google Sheet, click Tools Script editor from the Google Sheets menu:
2. Declare Class Variables
Create a handful of class variables to be available for any functions created in the script.
//replace the variables in this block with real values as needed var address = 'tds.cdata.com:14333'; var user = 'CONNECT_USER'; // [email protected] var userPwd = 'CONNECT_USER_PAT'; var db = 'API1'; var dbUrl = 'jdbc:sqlserver://' + address + ';databaseName=' + db;
3. Add a Menu Option
This function adds a menu option to your Google Sheet, allowing you to use the UI to call your function.
function onOpen() {
var spreadsheet = SpreadsheetApp.getActive();
var menuItems = [
{name: 'Write data to a sheet', functionName: 'connectToAPIData'}
];
spreadsheet.addMenu('Typeform Data', menuItems);
}
4. Write a Helper Function
This function is used to find the first empty row in a spreadsheet.
/*
* Finds the first empty row in a spreadsheet by scanning an array of columns
* @return The row number of the first empty row.
*/
function getFirstEmptyRowByColumnArray(spreadSheet, column) {
var column = spreadSheet.getRange(column + ":" + column);
var values = column.getValues(); // get all data in one call
var ct = 0;
while ( values[ct] && values[ct][0] != "" ) {
ct++;
}
return (ct+1);
}
5. Write a Function to Write Typeform Data to a Spreadsheet
The function below writes the Typeform data, using the Google Apps Script JDBC functionality to connect to Connect AI, SELECT data, and populate a spreadsheet. When the script is run, two input boxes will appear:
The first one asks the user to input the name of a sheet to hold the data (if the spreadsheet does not exist, the function creates it).
The second asks the user to input the name of a Typeform table to read. If an invalid table is chosen, an error message appears and the function is exited.
Note, while the function is designed for use as a menu option, you can extend it for use as a spreadsheet formula.
/*
* Reads data from a specified Typeform 'table' and writes it to the specified sheet.
* (If the specified sheet does not exist, it is created.)
*/
function connectToAPIData() {
var thisWorkbook = SpreadsheetApp.getActive();
//select a sheet and create it if it does not exist
var selectedSheet = Browser.inputBox('Which sheet would you like the data to post to?',Browser.Buttons.OK_CANCEL);
if (selectedSheet == 'cancel')
return;
if (thisWorkbook.getSheetByName(selectedSheet) == null)
thisWorkbook.insertSheet(selectedSheet);
var resultSheet = thisWorkbook.getSheetByName(selectedSheet);
var rowNum = 2;
//select a Typeform 'table'
var table = Browser.inputBox('Which table would you like to pull data from?',Browser.Buttons.OK_CANCEL);
if (table == 'cancel')
return;
var name = Jdbc.getConnection(dbUrl, {
user: user,
password: userPwd
}
);
//confirm that var table is a valid table/view
var dbMetaData = name.getMetaData();
var tableSet = dbMetaData.getTables(null, null, table, null);
var validTable = false;
while (tableSet.next()) {
var tempTable = tableSet.getString(3);
if (table.toUpperCase() == tempTable.toUpperCase()){
table = tempTable;
validTable = true;
break;
}
}
tableSet.close();
if (!validTable) {
Browser.msgBox("Invalid table name: " + table, Browser.Buttons.OK);
return;
}
var stmt = name.createStatement();
var results = stmt.executeQuery('SELECT * FROM ' + table);
var rsmd = results.getMetaData();
var numCols = rsmd.getColumnCount();
//if the sheet is empty, populate the first row with the headers
var firstEmptyRow = getFirstEmptyRowByColumnArray(resultSheet, "A");
if (firstEmptyRow == 1) {
//collect column names
var headers = new Array(new Array(numCols));
for (var col = 0; col < numCols; col++){
headers[0][col] = rsmd.getColumnName(col+1);
}
resultSheet.getRange(1, 1, headers.length, headers[0].length).setValues(headers);
} else {
rowNum = firstEmptyRow;
}
//write rows of Typeform data to the sheet
var values = new Array(new Array(numCols));
while (results.next()) {
for (var col = 0; col < numCols; col++) {
values[0][col] = results.getString(col + 1);
}
resultSheet.getRange(rowNum, 1, 1, numCols).setValues(values);
rowNum++;
}
results.close();
stmt.close();
}
When the function is completed, you have a spreadsheet populated with your Typeform data, and you can now leverage all of the calculating, graphing, and charting functionality of Google Sheets anywhere you have access to the Internet.
