Hi All,
Simple question but....
Where do I find the excel file ID?
// ID of Excel file to convert

When working with google sheets files it's easy to find in the url but here I'm lost?

Thanks

Hi

i have mentioned the destination folder id in the variable destFolders still my file is getting saved in root drive .
is there something needs to be edited in the API script ? ( some thing to be changed in between line 34 and 37 ) ???

var xlsBlob = xlsFile.getBlob(); // Blob source of Excel file for conversion
var xlsFilename = xlsFile.getName(); // File name to give to converted file; defaults to same as source file
var destFolders = ['0B2IBO64RQ9WEFDEUTWFCZVhTQ1pk']; // array of IDs of Drive folders to put converted file in; empty array = root folder
var ss = convertExcel2Sheets(xlsBlob, xlsFilename, destFolders);

I remove below line from original code since isArray doesn't work in google script. I don't know why....
// if ( !parents.isArray ) parents = []; // make sure parents is an array, reset to empty array if not
then put the ID string like you did, it success to export spreadsheet into your assigned folder.
var destFolders = ['Folder ID String']; // array of IDs of Drive folders to put converted file in; empty array = root folder
I hope it helps.

Thanks for that David, been pounding my head against the wall over it! Should have checked here first.

Is it possible to automate this script? I'm over my head here, but need a way to take uploaded xlsm files and have them be converted to sheets files in "bulk". I've figured out how to get this script to work, but it appears to be set up for an individual file and not to loop thru a folder and convert what it finds there.

Any one else getting errors on pinging UrlFetchApp.fetch('https://www.googleapis.com/upload/drive/v2/files/?uploadType=media&convert=true', uploadParams);?

Nvm...a zip file slipped in there I think.

This code has worked for me. Thanks a lot.
While the code works for XLS which are self contained ( cells dont refer to other XLS files ), it doesnt work for XLS which have cells
with links to another XLS ( and that XLS is not available to you, like in the attached image ). XLS itself shows the value but warns about the missing reference file.

The converted sheet has REF! as the cell values where there is a reference in the XLS.

xls_ref

Is there a way to read the values in the XLS rather than the referred values

about the isArray - here is a working line for it:

if ( !Array.isArray(parents) ) parents = []; // make sure parents is an array, reset to empty array if not

Thank you very much for this post.

I have a question. Could you please share feedback if you have time.

I have a googleform that collects excel file from the users and uploads to the google drive. As I understand, I should transfer from excel file to spreadsheet to open and get the data. So I use “Drive.Files.insert()” to convert the file (as you mentioned), which requires additional approvals for the script. I enabled the Google Drive API under Resources > Advanced Google Services on google script and linked this google script to a google cloud project. Google Drive API is also enabled on google cloud with “OAuth 2.0 Client IDs “. But my script still cannot pass the google login process and only returns a word file with a google login page.

the script:
var Blob01 = UrlFetchApp.fetch(thelink).getBlob();
var fileInfo = { title: “test1”, mimeType: MimeType.GOOGLE_SHEETS, “parents”: [{‘id’: FolderId}], };
Drive.Files.insert(fileInfo, Blob01, {convert: true});

OAuth settings: Scopes for Google APIs >> ../auth/drive and ../auth/drive.file credentials: OAuth client ID >> Web application google drive API has been enabled and credentials are added as “Google Drive API” & “web browser” & “User data”

If the xls file is hosted on another website as a link, what would I need to modify to skip the google drive part?

This is a really useful script, but for those who are more versed in scripts. I tried for a long time to explain to my colleague how to use it, but it was hard for him, so I found an easier way to convert, and here it is https://blog.coupler.io/convert-excel-to-google-sheets/

Hello. I'm self-learning google scripts so please bear with me. I have a great need for this script. Basically, I have a Google sheet that I am manually importing three separate Microsoft Excel files into in order to be used by another google sheet that uses this imported data as a set of data using import ranges to generate various data break downs and charts based on this import data set. Since the three files I'm importing are large (I can't put all of them in on Google Sheets because it says I need more lines, but I can't), I have to use this method. I know this is a lot of data, but that's what I'm dealing with, and it needs to be overwritten every four hours. https://www.mirajwala.com/
