Scenario:
An accounting team exports a quarterly report from their internal system to XLSX. The file opens in Excel but all formula references are broken, two worksheets are missing, and date columns display as integers.
What we did:
We identified the export configuration error that caused formula references to shift, recovered the missing sheet data from the workbook's internal cache, and corrected the date format mapping. The corrected file was returned with all formulas intact, all worksheets present, and dates displaying correctly.
