I'm extending a controller in CodeIgniter that handles PHPExcel. So far, I've not gotten anywhere near column Z, until now. Having arrived, I'm greeted with:
Fatal error: Uncaught exception 'Exception' with message 'Invalid cell coordinate AA' in /PATH/phpexcel/PHPExcel/Cell.php:513 Stack trace: #0 /PATH/phpexcel/PHPExcel/Worksheet.php(1119): PHPExcel_Cell::coordinateFromString('AA') #1 /PATH/phpexcel/PHPExcel/Worksheet.php(1022): PHPExcel_Worksheet->getCell('AA') #2 /PATH/application/modules/bookings/controllers/export.php(138): PHPExcel_Worksheet->setCellValue('AA', 'Purchase Order ...') #3 [internal function]: Export->index() #4 /PATH/system/core/CodeIgniter.php(297): call_user_func_array(Array, Array) #5 /PATH/index.php(163): require_once('/PATH...') #6 {main} thrown in /PATH/phpexcel/PHPExcel/Cell.php on line 513
I've written some code to generate AB-AZ BB-BZ columns, but — as you can see above — PHPExcel isn't having it.
$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_sqlite;

unset($objPHPExcel);Line 138 is:
$objPHPExcel->getActiveSheet()->setCellValue($array_column_indices[$x], $array_values_options['label']);Just to reiterate, everything was smooth as silk until I added more columns in the MySQL query.
PHPExcel is something of a mystery to me, so any assistance would be wonderful.
Edit 11 June, 10:05am GMT
I've made some changes to the for() loops:
$a=1;
$p=1;
$r=0;
for ($s=65; $s<=90; $s++): // Assign the letters of the alphabet. for ($i=65; $i<=90; $i++): if (chr($s) == "A"): $array_column_indices[$a] = chr($i) . $p; else: $array_column_indices[$a] = chr($s-1) . chr($i) . $p; endif; $a++; endfor; $r++;
endfor;While this has gotten around the column Z problem, I'm seeing strange things in the spreadsheet:
- After the column names in row 1, I have 10 row gap of empty cells.
- A block of 8 rows with data.
- 13 rows of empty cells.
- A row containing a number of cells with SUM() formula in them.
- Almost a 100 rows of empty cells.
- A block of 23 rows with data.
8 + 23 = 31 rows of data, which is correct, but as to why the formulas are in between, and the gaps? No idea.
So, 2 steps forwards, 1 step backward.

From the stack dump, you're trying to get cell 'AA', which isn't a valid Excel cell reference... it's missing a row number:
PHPExcel_Worksheet->setCellValue('AA', 'Purchase Order ...')Note that there is a built-in function that can convert a column number to a column name, PHPExcel_Cell::stringFromColumnIndex() or you can take advantage of PHP's ability to increment strings PERL-style, or (if you prefer to work with numbers for columns) use the worksheet's setCellValueByColumnAndRow() method
In the end, what I had was close, but required a few tweaks:
$columns = ( ... count(of columns) ... );
$iterator_for_column_range=1;
// Assign the letters of the alphabet to the column ranges.
for ($x = 65; $x <= 90; $x++): for ($y = 65; $y <= 90; $y++): if (chr($x) == "A"): $array_column_indices[$iterator_for_column_range] = chr($y); else: $array_column_indices[$iterator_for_column_range] = chr($x-1) . chr($y); endif; if ($iterator_for_column_range == $columns) break; $iterator_for_column_range++; endfor;
endfor;Here, the $columns variable stops the columns from running on.
Also, made changes in the foreach loops to the iterator variables, so that they only iterate once each pass:
$objPHPExcel->getActiveSheet()->setCellValue($array_column_indices[**$index_of_columns_for_column_name**] . **$index_of_range**, $arrayAttr['results']['config_database_tables']['tables'][$arrayAttr['results']['group']]['bookings'][$keys]);Done!
In my case,a filter was used in excel file, and to solve the problem, I copied the data from the file and paste it into a new excel file without any format.
