FAQs

Q: How does CSV to Notion handle column mismatches?

You define a schema. Users map their columns to required fields; unmapped/invalid fields are flagged with inline errors before upload.

Q: Can I upsert into Notion using a unique key?

Yes. Set one or more keys (e.g., sku, email). Rows with matching keys are updated; others are inserted.

Q: What file sizes are supported?

Typical imports handle 50k–200k rows depending on validations and destination throughput. Contact us for higher limits.

Q: Do you support server-side validation?

Yes. Send rows to your validation endpoint to approve/transform data before final write.

Q: Is data encrypted and compliant?

Data is encrypted in transit and at rest. CSVBox supports GDPR features and follows SOC 2–oriented practices.
