The file name format for exported Salesforce reports differs between 'Formatted Report' and 'Details Only' export options, and also varies by file format (.xlsx vs. .xls or .csv).
The file name of an exported report is determined as follows based on the export format.
[Alphanumeric characters from Report Name]+[-YYYY-MM-DD-HH-MM-SS].xlsxExample: test-2025-01-01-00-00-00.xlsx
Note: If the report name contains multi-byte characters, those characters are excluded from the file name.
report[epoch milliseconds].xls or report[epoch milliseconds].csvExample: report1702341744860.xls
Supplement: The "epoch milliseconds" in the file name represents the number of milliseconds that have elapsed since January 1, 1970, 00:00:00 (UTC). You can use an external conversion website to determine the exact export date and time.
