Question

I am trying to fetch a gzip from a URL and import it automatically into a Google Sheets. The gzip contains one file of CSV data.

I know I can import the CSV data into a Google Sheets but I would like to be able to cut out the step of me having to download the gzip and extract the file first before uploading it into a Google Sheets.

So my queries:

Is it possible to import a gzipped CSV file from a URL directly into a Google Sheets?

If not, how would this be done with a Google Apps Script?

Answer 1

There is an undocumented utility in GAS called unzip, I know it can unzip ordinary .zip files but have no idea if GNU zip are supported… maybe it’s worth give it a try ?
here is a quick test I wrote for a zip that was in my google documents/drive

function testzip(){
var files=DocsList.getRootFolder().find('Sans titre.txt.zip');
var zipblob=files[0].getBlob();
var unzipblob = Utilities.unzip(zipblob);
var unzipstr=unzipblob[0].getDataAsString();// it is a text file
DocsList.createFile('Sans titre.txt',unzipstr);// I kept the original name to make it simple
}

Don’t blame me if it doesn’t work for you… it’s just a proposal 😉
