Importing structured data into Notion shouldn’t be a hassle. Our tool simplifies the process with smart column mapping and duplicate prevention—ensuring a seamless and error-free experience. Save time and let your Notion data work for you. 🚀

What to expect from an ideal product
- Spaceloadr automatically detects matching records before importing to stop the same data from being added twice to your Notion database
- The tool checks existing entries against your new upload and flags potential duplicates so you can review them before they get saved
- Smart column mapping helps identify duplicate records even when data formats are slightly different between your source file and Notion
- You can set custom rules to define what counts as a duplicate based on specific fields like email addresses, product codes, or names
- The preview feature shows you exactly which entries will be skipped as duplicates before you complete the upload process
