Description: Cells with formulas referencing other cells that have special number formats (like currency) will attempt to inherit those number formats too. LibreOffice 4.1 changed the behavior for the “General” number format when used with formula format code inheritance. Unfortunately, "clear direct formating" or changing format back to "General" on these formula cells causes inconsistent behavior. The format code does, indeed, change back to "General," and the cell format does change, as you would expect. But when you save and reload the spreadsheet, the formula cells will revert to mimicking their referenced cells. According to the bug priority flowchart, I could argue that it does cause a loss of data in a component that affects many users. This would categorize it as Critical-High. It is also a regression, so that too would justify a higher priority. Since it's rather easy to work around, I'll set to Major High. https://wiki.documentfoundation.org/images/0/06/Prioritizing_Bugs_Flowchart.jpg I've tested a number of versions under different versions of Linux and MS Windows. This regression appears to have been introduced in version 4.1.0. Tested Affected Inconsistent Versions: LO 4.1.0.4 using 32bit Fedora 17 LO 4.1.4.2 using 64bit RHEL6 LO 4.2.1.1 using 32bit Fedora 17 LO 4.1.4.2 using 32bit Windows 7 Tested Versions with previous (consistent) behavior: OO 3.2.1 using 64bit RHEL6 LO 3.5.7.2 using 32bit Fedora 17 LO 4.0.6.2 using 32bit Fedora 17 Steps to reproduce: 1. Open new spreadsheet 2. In cell A1, insert a dollar amount ($100) 3. In cell B1, insert a formula pointing to A1 (=A1) 4. Note that B1 changed format to match A1 (should be currency) 5. Right click B1 and clear formatting 6. Note that B1 changed format from currency to a standard number format (100) 7. Save document 8. File -> Reload Expected: However your formatting looks when you save a document is how it should look when you load it. B1 should still have a standard number format “100” if that is how you saved it. Actual: B1 has changed format back to currency, ignoring our last formatting change to clear direct formatting. It looks very different than how we saved it. I have also included an example spreadsheet. Simply clear formatting on column B, save, and reload the document to see the error. Notes: This behavior seems rather complicated. I might be assuming too much about LO Dev's intentions, but it seems that LO changed the behavior of the “number-general” number format in version 4.1. Prior versions of OO/LO seem to use the “number-general” format as an “undefined format.” In our example, when you viewed B1's formatting, it wouldn't actually change from “number-general” to “currency” as it does now. It would remain number-general, but just APPEAR to be formatted as currency. Since there was no actual change of formats, only appearance, the change would be immediate and remain consistent between saves. Everything was at least everything was consistent, but rather confusing. In LO 4.1+, if you check the formula cells(B column) in the example, they are no longer formatted as number-general. They have now actually changed format code to mimic the cells they reference. It also seems that LO devs attempted to change the behavior for “number-general” to actually be a defined number format. When you clear formatting it now changes back to a normal number (integer). But the devs forgot to change the behavior for when you load the saved document. When the document is loaded, LO still processes “number-general” as undefined and applies the referenced cell's format. I agree with LO's decision to change this behavior. If I have currency cells, I would expect that formatting them back to number-general would format them the way they would appear if I just typed that value into a blank cell. Unfortunately, it's currently half implemented and leads to some horrible quality-of-work cases. One of my users recently sent a spreadsheet to another user and an entire derived column changed formats to currency. Work Around: An easy work-around is to change your formula's number format to a SPECIFIC number format code. For instance, change it to “0” instead of “General”. Unfortunately, I think it will be rather complicated to fix this bug without breaking compatibility with other LO/OO versions/possibly MS formats. But it is something that needs to be addressed.

Hi tmacalp, thanks for reporting. Clearing the format, when reopening the inherited format is restored. But if you set up a format (not clear), the new format is preserved after reload. The issue is still there with: Win7x64Ultimate Version: 4.2.2.1 Build ID: 3be8cda0bddd8e430d8cda1ebfd581265cca5a0f
Apparently, LO is saving the cleared format state, but ignoring that change on document load.

This behaviour changed over the course of a couple of commits. Before 57efd69c22e2c6f5cb4d057345644b6e07a62d48, the =A1 reference doesn't have an independent format that can be reset or altered. From e18f5306714e6ca4103dd236bcf3187d492cbb91 onwards (modulo a merge error fixing commit which follows), the current situation where the format can be reset but doesn't roundtrip correctly occurs.
