Does Flookup transmit spreadsheet data to any third party?

    • No, Flookup does not transmit spreadsheet data to anyone.

Does Flookup store the spreadsheet data it processes?

    • No, Flookup does not store any spreadsheet data it processes; we do not have any need to do so.

I subscribed but I still don't have the Premium Plan features

Here are a few things you can do to resolve this issue:

    • Give it a few minutes. When you subscribe, your premium experience is unlocked immediately. However, in some rare cases, there might be a delay because of server synchronization but this does not take more than 10 minutes.
    • Review your subscription status by heading to Add-ons > Flookup > About Flookup in the spreadsheet menu.
    • Make that sure you entered the correct email address under Subscriber Email while subscribing.

Flookup is just not working as advertised

    • There is an open issue that revolves around errors you might experience when installing or using add-ons while signed into 2 different accounts. Please verify that this is not the case by signing out of one account or using Flookup in incognito mode.
    • If you have more than one user accessing a single spreadsheet, you may either subscribe for one of our Enterprise plans or you remove the extra users.

Does Flookup have an API available?

    • No, not yet.

Is Flookup free?

    • No, but Flookup has a free unlimited trial available for 7 days.


Add-ons that request certain sensitive OAuth scopes (permissions) are subject to verification by Google. Below is a list of the OAuth scopes that we were granted permission to use with Flookup (after completing the said verification) and a brief description of how we use them:

Connect to an external service

    • Flookup connects to a database within Google's ecosystem (https://firebase.google.com) to retrieve subscription information. This information, which is retrieved from PayPal, includes your email address, amount you paid and the subscription plan you are on.

View your email address

    • Flookup has functions that display prompts to communicate important messages to you or to initiate certain functions. This scope is necessary to accomplish that.

Display and run third-party web content in prompts and sidebars inside Google applications

    • Flookup views your email address strictly for the purposes managing your subscription.

View and manage spreadsheets that this application has been installed in

    • This allows Flookup to read and write data to the spreadsheet it has been installed in.



    • Try reloading the spreadsheet or reducing the number of cells that are concurrently performing calculations.

Internal error executing the custom function.

    • This error means that the function timed out because Google only allows 30 seconds of execution for custom functions . Reducing workloads usually resolves the issue.

Service invoked too many times in a short time: exec qps. Try Utilities.sleep(1000) between calls.

    • Try entering a range as an argument, instead of entering a single cell, if the function allows it. Please see the documentation to find out how.


    • First, ensure that you have typed the correct function name and then, if that fails, try reinstalling Flookup, reloading the spreadsheet or running any of the Flookup functions in the add-on menu.


Hover your cursor over the cell containing the error and a tooltip showing the details of the error will be displayed. The message you see means one of the following issues is at play:

    • No result was found.
    • There is an error in your syntax.
    • Your subscription is inactive or your current usage requires an Enterprise License.
