GAS Folders, Sub Folders and their Files

Google Drive is a wonderful thing, but when it comes to getting at a file with scripts things can get a little quirky. Every file and folder has a unique ID number (28 digits, letters and other marks) which can make it easy to locate it, if you know how. However you can of course have many files, or folders with the same name spread out across your Google Drive, which can create a bit of a problem when trying to find the file or folder. Very often you may have to iterate over “all the folders” in order to find what you want, using names to do this can be problematic.

I find I am routinely needing to grab a list of filenames, file IDs, or file types, and routinely searching the web each time I need to do this, therefore it was about time I tied down the required scripts in one place for reuse. The scripts I have put together will request either a folder name or ID in order to iterate over the files within that folder and return the results to a spreadsheet. The scripts can be used as a base, and edited to suit specific requirements by adding further properties to return, or through the use of if statements to narrow down selected files.

  • You can find the ID of the folder by looking in the url address bar if you have the folder open in Google Drive
  • You can also right click on the folder and then Shareable Link
  • Finding the name should be obvious! – use search in Google Drive to check for folders with the same name. It may be wise to do this occasionally if you use name a lot in your scripts, and to make your folder names unique

In my scripts I have chosen to return the filename, the mime type, the file ID, and to create a download link. I also include a helper script (courtesy of Sandy Good) that presents the mimetype in a more user friendly way. All four folder scripts rely on this. Thanks should also go to Brian P and AD:AM on the google group support forum for their code.

I will add a link to a google sheet which contains all the scripts, just make a copy of it to your own google drive, authorise the scripts and away you go.

GAS Import CSV from GMail Attachment

I have a weekly email sent to me with a csv attachment. This needs to be opened and the contents pasted into a google sheet, the data therein is then used for a variety of other applications running on Google sheets. Fortunately there is a way to automate this and to parse the csv to sheets. I have robbed and amended the code provided by Digital Inspiration to do this. The linked page also includes other examples of scraping csv data from an email attachment. The key to getting this to work is a consistent approach by my email sender, who needs to use the same email address and subject in order that the GMail filter I set up can assign a label to the email. The script is run from the receiving google sheet on a timed trigger, once a week.

The sheet needed sorting to meet requirements of others. Above code kept nice and short thanks to the parsing API provided by Google. Of course, this will work for a single user google account, calling on the gmail of that user. Because I have G Suite it is simple to create a separate account to handle this type of thing.
