How it works

How OneSchema automates messy data importing

1
Define your target data schema
OneSchema supports 50+ prebuilt validations and transformations.
Write highly performant custom code validations that can be managed from OneSchema or your own codebase.
2
Record cleaning a sample file to define mappings & transformations
Have a data analyst clean a file once to teach OneSchema how to clean future files.
Transformations will be replayed on future uploaded files.
3
Turn on your FileFeed & route errors
View all files that failed validation to be viewed in a single place, with detailed information about the errors.
Send customers emails with a link to fix issues in the file by themselves.
Notify your internal team via email, Slack, or in your monitoring tools.

THe Oneschema difference

Not just another no-code integration builder

Specialized for CSVs and other file formats
We know file formats are especially error prone and are built to handle them. We've seen millions of CSVs, XLSX, and XML files to build out our proprietary parser.
Record & replay transformations
Define your transformations by recording a non-technical user cleaning a file. No training required.
Validation as a core feature
Since files are so error-prone, we've built in powerful validation logic to shield your database against bad data.
