Occors in xlsx format (for Excell): 1- Format cell as text. 2- Type a time in the cell for ex 01:39:20 (1 hour 39 minutes 20 seconds). (But look: I want TEXT format preserved later, not time format, because I want to use hour, minutes and seconds in a formula that expects 8 characters!). 3- Save the sheet as xlsx type and close it. (Before closing it's ok). 4- Reopen it: you will see that there is a strange number in the cell and it is formatted as number. Data is not lost, because if you open using Excell it's ok. But I want to see my data the way I typed it using Libreoffice or I will change for Excell! Thanks
reproduced with LO 3.6.1.2 (Windows), but after reopening this cell is formatted as text, but shows a number 0,0689.... in Excel 2007 it is correct
Known problem from "Bug 55091 - FILEOPEN .xlsx shows text dates DD.MM.YYYY as integer numbers with existing date recognition pattern D.M.Y" @Marcio Jacques Thank you for your attention!
