How to sync large number of rows to Google Sheets?

In Youform's Google Sheets integration, after you attach a sheet, you can sync your previous data to the Google Sheets using the sync button on the integration page.
But sometimes, you might have already accumulated a lot of data (more than 5000) and the sync of the old data will not work. In that case, you need to add the old data to your sheet manually. Here is how you can do it:
    Connect a Google Sheet from the integrations page (if you have not already done it).
    Go to your results tab and download the submissions.
    Open the downloaded CSV in  Google Sheets  and remove the first row and first column
    Download it as a CSV
    Open the Google Sheet that is attached to your form
    On the Google Sheets page, go to File > Import > Upload tab and upload your current old data CSV file (that you downloaded in step 4).
    Once done, there will be an option to add this data to the current sheet. You need to choose "Append to current sheet" option
Done! All your previous data will be added to the sheet, and as your sheet is attached to the form, so the new data will also keep coming in.
