Product documentation
Supported tabular formats
The current structured-file routing recognizes:
.xls.xlsx.csv
These extensions can be offered to Documents (Excel) after upload to the Document Library. Extension recognition does not guarantee successful parsing: damaged content, unsupported workbook features, encoding, size, or service conditions can still cause failure.
Documents (Excel) preserves parsed worksheet metadata, while source cell values and workbook structure are not edited by the metadata form.
