--- Comment #2 from Haider <ali.haider.s...@gmail.com> --- Thank you for the test case in r1914511. We're encountering an issue in our application, which allows users to modify Excel files stored on S3 via a front-end interface, as well as through MS Online and SpreadJS. The problem arises during formula recalculation in sheets with names containing apostrophes, resulting in an 'Invalid sheetIndex: -1' error. It's not entirely clear if the error is due to modifications made through MS Online/SpreadJS or another factor. To provide more context, our POI service receives the Excel file URL and the specific cell that needs to be updated. We locate and update the cell in the workbook and then initiate formula evaluation. Despite the formulas appearing correct in our logs, POI consistently returns the 'sheetIndex: -1' error. We would greatly appreciate any insights or suggestions for alternative approaches to this problem. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
