Inconsistent treatment of zero-length string
Last modified: 2017-05-20 10:45:24 UTC
(a) Importing an Excel XLSX or XLS file that contains a zero-length string: If cell is a zero-length string result of a formula (simplest example: =""), it works OK: COUNTA(cell) -> 1, ISBLANK(cell) -> FALSE, ISTEXT(cell) -> TRUE. However if cell is not the result of a formula (e.g. entered manually in Excel UI by typing '<Enter> or by copy a formula and Paste Special without formula), it treats it like a blank/empty cell: COUNTA(cell) -> 0, ISBLANK(cell) -> TRUE, ISTEXT(cell) -> FALSE. (b) There appears to be no way of manually entering a non-formula zero-length string through the Calc UI: (b1) Typing '<Enter> results in a 1-length string containing the apostrophe. (b2) Copy a cell with ="" formula and Paste Special (no formula) results in a blank/empty cell.
