Created attachment 35663 [details] Sample test file with one sheet, and two cells. https://issues.apache.org/jira/browse/TIKA-2196 This seems to be happening when a cell is set to custom format with double quotes, for example: ""ddd,mmm dd or ""dddd, mmmm dd, yyyy As per, https://bz.apache.org/bugzilla/show_bug.cgi?id=54786 the double double quotes are replaced by a single single quote. However in this case, there is no closing single quote.
