Actually in the process of integrating CSVBox.
What I can tell you :
- The support is very responsive concerning both technical and data privacy questions. i had a few remarks concerning their French translations, and they are already fixing it.
- Their price (less than $50/month for most use cases) is much cheaper than other alternatives on the market : Flatfile, OneSchema, etc...
- They support multiple destinations, including Bubble.io and I believe they are the only software doing that for a no-code tool.
- Their changelog is active in February 2022 (month of my comment), which is good news.
