How Do I Unprotect a Cell in OpenOffice Calc?
By default, a protected spreadsheet in OpenOffice Calc 4 protects every cell, preventing anyone from editing their contents. To unprotect specific cells on the sheet, you first need to turn off protection for the entire sheet. Set the specific cells to not use protection, and then re-enable sheet protection on the rest of the sheet.
Open the **Tools** menu, point to **Protect Document** and uncheck **Sheet**. If the spreadsheet's creator locked the sheet using a password, you'll need it to turn off protection.
Select the cells you want to unprotect by clicking and dragging, clicking a column or row header, or holding **Ctrl** while clicking each cell. Open the **Format** menu and click **Cells** to format the selection.
Turn off **Protected** on the Cell Protection tab and click **OK**.
Reopen the **Tools** menu and click **Sheet** in the Protect Document section when you're ready to reprotect the rest of the spreadsheet.
Enter a password if you want one, and click **OK** to turn on protection. The cells you formatted remain unprotected and editable, while the rest of the sheet locks down.
Tips & Warnings
- Cell formatting remains applied even if you unprotect and reprotect the sheet in the future -- you don't need to perform these steps every time you unlock the sheet for editing.
- Don't confuse document protection with sheet protection. Protecting the document as a whole prevents the creation, deletion or renaming of entire sheets, but does not lock cell contents.
