How can I upload Yotpo product reviews to Google Merchant Center?

I’m trying to figure out a way to upload Yotpo product reviews to Google Merchant Center. I know yotpo offers automated integration if you upgrade but their plans are very expensive and I’m a small business with low volume so the cost is prohibitive. I have tried going about it manually by exporting the CSV file then uploading it into GMC but I get an XML processing error:

"Our system encountered an error when processing your XML data feed. Please see the following Help Center topics for more information:

XML tag mismatch

Invalid RSS/Atom document format"

Does anyone know how to format the CVS file exported from Yotpo into one that will be accepted/readable by GMC? Or any other type of workaround.

Setting up a manual review feed, will most likely not work. And you may cause more harm to your business. Because the reviews need very specific information to validate it’s authenticity. Such as customer info, and product info.

However if you want to manually set it up, which I don’t recommend. Then here is the guide: https://support.google.com/merchants/answer/7075701?hl=en
