Receipt apps that sync to Google Sheets usually cost a monthly subscription. If you just need your receipts in Google Sheets, a CSV is enough.
Download the CSV, then in Google Sheets use File → Import → Upload and choose "Insert new sheet". Dates import as real dates so you can pivot by month.
Privacy: images never leave your device. Free: 5 receipts per batch. Pro ($19 lifetime): unlimited batches + QuickBooks/Xero CSV layouts.
