When performing an export using the Export Data Store Entity to Excel Smart Service and providing a "Document To Update" that is an existing Excel file, one the following errors might be encountered:
The decompressed version is 100x larger than compressed version. Unable to update file <FILE_NAME>. The file size of the 'Document to Update' is at least 100 times larger when uncompressed, which constitutes a security risk.
The decompressed version has a zip entry that is >4GB. Unable to update file <FILE_NAME>. The file size of the uncompressed 'Document to Update' is too large.
Ensure that the Excel file is not a zip bomb. Inspect the Excel file for duplicated data, styles, or other metadata that may contribute to this issue and re-save the file before using it with this smart service. If a file has all formatting removed and the error persists, then the file is too large to be updated.
