How to create a spreadsheet with an associated script? - google-apps-script

Question

I'd like to programatically create a batch of spreadsheets which contain different data, but all of which contain a button that is associated with a custom backend function.
For example, each spreadsheet should have a button that, when pressed exports the data to another sheet.
Is such a thing possible?
One idea I had was maybe to create a template that includes the button and associated Apps Script and then make a copy of that spreadsheet and fill it with the custom data.

The Apps-Script API allows you to programmatically create Apps Script projects with the option of binding them to a Google Sheet
Convert your project into a Cloud Platform project and enable Apps Script API for this project
Give your projects the necessary scopes in the manifest file
Incorporate Apps Script API into Apps Script with a Urlfetch request
Create a new Apps Script Project with Method: projects.create specifying the parentId
Add contents to the project with Method: projects.updateContent. You can store the contents in a variable and thus add the same content to all of your Apps Script projects.
Sample:
JSON file
{
"timeZone": "America/New_York",
"oauthScopes": [
"https://www.googleapis.com/auth/spreadsheets",
"https://www.googleapis.com/auth/script.projects",
"https://www.googleapis.com/auth/script.external_request"
],
"dependencies": {
},
"exceptionLogging": "STACKDRIVER"
}
.gs file
function createSpreadsheetwithScript() {
var ss=SpreadsheetApp.create('mySpreadsheet');
var id=ss.getId();
var token = ScriptApp.getOAuthToken();
var url = "https://script.googleapis.com/v1/projects";
var payload = {
"title": "myAutoCreatedScript",
"parentId": id
}
var options = {
"method" : "POST",
"muteHttpExceptions": true,
"headers": {
'Authorization': 'Bearer ' + token
},
"contentType": "application/json",
"payload": JSON.stringify(payload)
}
var response = UrlFetchApp.fetch(url,options);
var scriptId=JSON.parse(response).scriptId;
var url2="https://script.googleapis.com/v1/projects/"+scriptId+"/content";
//test content
var source="function myFunction() {\n var x=1;\n}";
var JSONsource="{\"timeZone\":\"America/New_York\",\"exceptionLogging\":\"STACKDRIVER\"}";
var payload2 = {
"files": [
{
"name": "this is the gs. file",
"type": "SERVER_JS",
"source": source
},
{
"name": "appsscript",
"type": "JSON",
"source": JSONsource,
"updateTime":"2018-03-04T19:49:08.871Z",
"functionSet":{
"values":[{"name":"myFunction"}]}
}
]
}
var options2 = {
"headers": {
'Authorization': 'Bearer ' + token,
},
"contentType": "application/vnd.google-apps.script+json",
"method" : "PUT",
"payload": JSON.stringify(payload2)
}
var response2 = UrlFetchApp.fetch(url2,options2);
}
Make sure to enable the Apps-script API before using it under https://script.google.com/home/usersettings and that your upadteContent request inclusdes a manifest file

To write a custom function:
Create or open a spreadsheet in Google Sheets.
Select the menu item Tools > Script editor. If you are presented with a welcome screen, click Blank Project on the left to start a new project.
Delete any code in the script editor....
Select the menu item File > Save....
All done!
