Supported document formats

The Document Library upload dialog displays the extension list configured for the current environment. That displayed list is the authoritative client-side upload allowlist for the current session.

Verification rules

• Validation uses the final filename extension, case-insensitively.
• Files without an allowed extension are rejected before upload.
• The interface accepts at most 100 files in one selected upload batch.
• Per-file size limits come from runtime configuration. Tabular extensions (.xls, .xlsx, .csv) use the configured table-file limit; other allowed types use the general limit. DataFact cloud currently sets both limits to 200 MB.
• When a finite total storage allowance is returned, the upload dialog shows current usage and prevents a selected batch that would exceed the remaining allowance.

Upload eligibility does not guarantee preview, parsing, chunking, or Agent compatibility. Each downstream workflow applies its own rules.
