How to Use .searchFiles() in Google Script Custom Functions

Google Sheets is a powerful tool for both personal and professional projects, allowing users to store and analyze data. However, when working with Google Apps Script, particularly custom functions, you may face certain limitations, especially regarding permissions. One common issue is trying to use the .searchFiles() method from the DriveApp class in a custom function, which often results in a permissions error. In this guide, we’ll explore how to effectively use the .searchFiles() function in Google Script and offer a workaround to make it operational within your Google Sheets environment.

The Challenge: Permissions Error

Many users have encountered the frustrating error message:

This occurs because Google Apps Script custom functions are sandboxed for security reasons, which restricts certain functionalities like accessing files in Google Drive via the DriveApp. But don’t worry! There’s a straightforward solution that allows you to accomplish your goal without running into permissions issues.

The Solution: Create a Custom Menu

Instead of calling .searchFiles() directly within a custom function, you can create an onOpen() function that sets up a custom menu in your Google Sheets. This menu can invoke the desired function without the restrictive permissions limitation.

Here’s how to implement it:

Write Your FindID Function:
Start with your initial function, which searches for files that match a given date.

Create the onOpen() Function:
This function creates a custom menu when the spreadsheet is opened, allowing users to execute the FindID function easily.

Using the Menu:
After implementing the above code, every time you open your Google Sheet, a new menu called "File Search" will appear at the top. Click on it, and you will be able to run the FindID function without encountering the permissions error.

Benefits of This Approach

Bypassing Permissions Issues: This method elegantly circumvents the limitations of custom functions while still allowing for file searches.

Enhanced User Experience: Custom menus improve accessibility and usability for users who may not be familiar with script execution.

Flexible: You can easily modify the FindID function to incorporate additional features, such as returning results directly in the spreadsheet.

Conclusion

Implementing .searchFiles() within Google Apps Script can be challenging due to permission constraints. However, by creating a custom menu within your Google Sheets, you can fully utilize the power of Google Drive's file searching capabilities without hitting roadblocks.

Now that you are equipped with the necessary tools to execute this functionality, your data management in Google Sheets can become significantly more efficient. Happy scripting!
