The IATI Validator is an online tool for checking if data aligns with the rules and guidance of the IATI Standard. It allows users to check and improve the quality of IATI data to ensure it is accessible and useful to anyone working with data on development and humanitarian resources and results.

How the IATI Validator works
The IATI Validator performs checks on IATI data files and returns error and warning messages about how to correct the data. There are three ways to use the IATI Validator.
- Check data: anyone can upload their IATI data files to be checked before publishing them.
- Public data viewer: anyone can check all IATI data files that have been published.
- Validator API: technical users can intergrate the Validator API into their internal data systems for periodic data checks
Messages to identify errors
The Validator displays a message for each occurrence of data that does not comply with the IATI Standard. The message identifies what data needs to be corrected and where it occurs in the data file. A count of errors is also displayed, which shows how many times an error is repeated throughout a file. For example, if all activities in a dataset have omitted activity dates, then the user will see a count of this repeated error, as well as the location of each error.
Deprecation of old Public Validator
The old Public Validator was decommissioned on 22 March 2021 and users are advised to move over to using the IATI Validator as soon as possible. If you have any questions about the old Public Validator please contact the IATI Technical Team.
