 ### Tabular data check
 
-For all data files uploaded to Dryad in CSV, XLS, XLSX, and TSV formats (5MB or less), a report will be automatically generated by our tabular data checker, an integration with the [Frictionless framework](https://frictionlessdata.io/). This integration allows for automated data validation, focused on the format and structure of tabular data files, prior to our curation services. JSON and XML files are also checked for basic file validity.

JSON and XML files are also checked for basic file validity.
 
 If any potential inconsistencies are identified, instructions will appear on the "Upload files" page, and a link to a detailed report will be provided for each affected file in the "Tabular data check" column. The report will guide you in locating and evaluating inconsistencies in your tabular data. Any files flagged in the report can be removed, edited, and reuploaded prior to proceeding with the submission process.
