I added a new menu item to my spreadsheet using google apps script. This menu item creates a file, but I'd like for it to initiate the download of the file after creating it.
Is this possible?
Remember, this is not a web app, but a menu item in my spreadsheet.
Edit:
Thanks to Serge insas' suggestion, the following simple script works perfectly, and opens a download window with the link I need:
function onOpen() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var csvMenuEntries = [ {name: "Zip all CSVs", functionName: "saveAsCSV"} ];
ss.addMenu("CSV", csvMenuEntries);
};
function saveAsCSV() {
var folder = createCSVs(); // creates a folder with CSV for each Sheet
var zipFile = zipCSVs(folder, "DI.zip"); // creates a zip of all CSVs in folder
var ui = UiApp.createApplication().setTitle("Download");
var p = ui.createVerticalPanel();
ui.add(p);
p.add(ui.createAnchor("Download", zipFile.getDownloadUrl()));
SpreadsheetApp.getActive().show(ui)
}
EDIT : read the comments below, Zig Mandel is perfectly right when he points out the limitations of the "complicated" version, it was really a simple (and fun) exercice to show other methods.
I think you'll have to use an intermediate Ui as a popup to confirm the download. After that there are 2 possible ways that I know, one is very simple and the other is quite cumbersome, make your choice, the code below shows both of them.
note : to use the complicated one you need to deploy your app (ie save a version and deploy as webapp), for the simple one just use it "as it is". (I show the simple in the code comments).
The code :
function onOpen() {
var menuEntries = [ {name: "test download", functionName: "downloadFile"}
];
var sheet = SpreadsheetApp.getActiveSpreadsheet();
sheet.addMenu("Utils",menuEntries);
}
function downloadFile(){
var file = DriveApp.createFile('test file', 'Some content in this file to test it');
var fileID = file.getId();
var fileName = file.getName();
var ui = UiApp.createApplication().setTitle('Download');
var url = ScriptApp.getService().getUrl()+'?&ID='+fileID+'&name='+fileName;
var p = ui.createVerticalPanel();
ui.add(p);
p.add(ui.createAnchor('click to download', url));
p.add(ui.createAnchor('or use this link ',file.getDownloadUrl()));// this is the simple one, just get the file you created and use getDownloadUrl()
SpreadsheetApp.getActive().show(ui)
}
function doGet(e){
var fileId = e.parameter.ID;
var fileName = e.parameter.name;
var fileString = DocsList.getFileById(fileId).getContentAsString();
return ContentService.createTextOutput(fileString).downloadAsFile(fileName);
}
PS : I had some fun writing this, the "complicated version" is really funny imho :-)
