Thanks for reaching out to Jotform Support. Please note that when you integrate your form with Google Sheets, it will send the data to the integrated sheet as soon as the form is submitted. Unfortunately, it is not possible to send the data to Google Spreadsheets only after the submission is approved or denied.
We've gone ahead and escalated your request to our developers, but when or if it's developed depends on their workload, how viable it is, and how many other users also request it. If there are any updates, we’ll circle back to this thread and let you know.
Thanks for your patience and understanding, we appreciate it.
