Installation

Use composer to install FastExcelWriter into your project:

composer require avadim/fast-excel-writer

Changes In Version 6

• Data Validation support

Important changes in version 6.1

• Sheet::setRowOptions(), Sheet::setColOptions(), Sheet::setRowStyles() and Sheet::setColStyles() are deprecated, instead of them you should use other functions: setRowStyle(), setRowStyleArray(), setRowDataStyle(), setRowDataStyleArray(), setColStyle(), setColStyleArray(), setColDataStyle(), setColDataStyleArray()
• The behavior of the Sheet::setRowStyle() and Sheet::setColStyle() has changed, they now set styles for the entire row or column (even if they are empty)

Changes In Version 5

• The general news is Chart support

Important changes in version 5.8

Before v.5.8

$sheet->writeCell(12345); // The number 12345 will be written into the cell
$sheet->writeCell('12345'); // The number 12345 will also be written here

In version 5.8 and later

$sheet->writeCell(12345); // The number 12345 will be written into the cell
$sheet->writeCell('12345'); // Here the string '12345' will be written into the cell

If you want to keep the previous behavior for backward compatibility, you should use option 'auto_convert_number' when creating a workbook.

$excel = Excel::create(['Sheet1'], ['auto_convert_number' => true]);
$sheet = $excel->sheet();
$sheet->writeCell('12345'); // String '12345' will be automatically converted to a number

Changes In Version 4

• Now the library works even faster
• Added a fluent interface for applying styles.
• New methods and code refactoring

FastExcelWriter vs PhpSpreadsheet

PhpSpreadsheet is a perfect library with wonderful features for reading and writing many document formats. FastExcelWriter can only write and only in XLSX format, but does it very fast and with minimal memory usage.

FastExcelWriter:

• 7-9 times faster
• uses less memory by 8-10 times
• supports writing huge 100K+ row spreadsheets
