Usage

You can find more examples in /demo folder

Simple example

use \avadim\FastExcelReader\Excel;

$file = __DIR__ . '/files/demo-00-simple.xlsx';

// Open XLSX-file
$excel = Excel::open($file);
// Read all values as a flat array from current sheet
$result = $excel->readCells();

You will get this array:

Array
(
    [A1] => 'col1'
    [B1] => 'col2'
    [A2] => 111
    [B2] => 'aaa'
    [A3] => 222
    [B3] => 'bbb'
)

// Read all rows in two-dimensional array (ROW x COL)
$result = $excel->readRows();

You will get this array:

Array
(
    [1] => Array
        (
            ['A'] => 'col1'
            ['B'] => 'col2'
        )
    [2] => Array
        (
            ['A'] => 111
            ['B'] => 'aaa'
        )
    [3] => Array
        (
            ['A'] => 222
            ['B'] => 'bbb'
        )
)

// Read all columns in two-dimensional array (COL x ROW)
$result = $excel->readColumns();

You will get this array:

Array
(
    [A] => Array
        (
            [1] => 'col1'
            [2] => 111
            [3] => 222
        )

    [B] => Array
        (
            [1] => 'col2'
            [2] => 'aaa'
            [3] => 'bbb'
        )

)

Read values row by row in loop

$sheet = $excel->sheet();
foreach ($sheet->nextRow() as $rowNum => $rowData) {
    // $rowData is array ['A' => ..., 'B' => ...]
    $addr = 'C' . $rowNum;
    if ($sheet->hasImage($addr)) {
        $sheet->saveImageTo($addr, $fullDirectoryPath);
    }
    // handling of $rowData here
    // ...
}

// OR
foreach ($sheet->nextRow() as $rowNum => $rowData) {
    // handling of $rowData here
    // ...
    // get image list from current row
    $imageList = $sheet->getImageListByRow();
    foreach ($imageList as $imageInfo) {
        $imageBlob = $sheet->getImageBlob($imageInfo['address']);
    }
}

// OR
foreach ($sheet->nextRow(['A' => 'One', 'B' => 'Two'], Excel::KEYS_FIRST_ROW) as $rowNum => $rowData) {
    // $rowData is array ['One' => ..., 'Two' => ...]
    // ...
}

Keys in resulting arrays

// Read rows and use the first row as column keys
$result = $excel->readRows(true);

You will get this result:

Array
(
    [2] => Array
        (
            ['col1'] => 111
            ['col2'] => 'aaa'
        )
    [3] => Array
        (
            ['col1'] => 222
            ['col2'] => 'bbb'
        )
)

The optional second argument specifies the result array keys

// Rows and cols start from zero
$result = $excel->readRows(false, Excel::KEYS_ZERO_BASED);

You will get this result:

Array
(
    [0] => Array
        (
            [0] => 'col1'
            [1] => 'col2'
        )
    [1] => Array
        (
            [0] => 111
            [1] => 'aaa'
        )
    [2] => Array
        (
            [0] => 222
            [1] => 'bbb'
        )
)

Allowed values of result mode

mode options	descriptions
KEYS_ORIGINAL	rows from '1', columns from 'A' (default)
KEYS_ROW_ZERO_BASED	rows from 0
KEYS_COL_ZERO_BASED	columns from 0
KEYS_ZERO_BASED	rows from 0, columns from 0 (same as KEYS_ROW_ZERO_BASED + KEYS_COL_ZERO_BASED)
KEYS_ROW_ONE_BASED	rows from 1
KEYS_COL_ONE_BASED	columns from 1
KEYS_ONE_BASED	rows from 1, columns from 1 (same as KEYS_ROW_ONE_BASED + KEYS_COL_ONE_BASED)

Additional options that can be combined with result modes

options	descriptions
KEYS_FIRST_ROW	the same as true in the first argument
KEYS_RELATIVE	index from top left cell of area (not sheet)
KEYS_SWAP	swap rows and columns

For example

$result = $excel->readRows(['A' => 'bee', 'B' => 'honey'], Excel::KEYS_FIRST_ROW | Excel::KEYS_ROW_ZERO_BASED);

You will get this result:

Array
(
    [0] => Array
        (
            [bee] => 111
            [honey] => 'aaa'
        )

    [1] => Array
        (
            [bee] => 222
            [honey] => 'bbb'
        )

)

Advanced example

use \avadim\FastExcelReader\Excel;

$file = __DIR__ . '/files/demo-02-advanced.xlsx';

$excel = Excel::open($file);

$result = [
    'sheets' => $excel->getSheetNames() // get all sheet names
];

$result['#1'] = $excel
    // select sheet by name
    ->selectSheet('Demo1') 
    // select area with data where the first row contains column keys
    ->setReadArea('B4:D11', true)  
    // set date format
    ->setDateFormat('Y-m-d') 
    // set key for column 'C' to 'Birthday'
    ->readRows(['C' => 'Birthday']); 

// read other arrays with custom column keys
// and in this case we define range by columns only
$columnKeys = ['B' => 'year', 'C' => 'value1', 'D' => 'value2'];
$result['#2'] = $excel
    ->selectSheet('Demo2', 'B:D')
    ->readRows($columnKeys);

$result['#3'] = $excel
    ->setReadArea('F5:H13')
    ->readRows($columnKeys);

You can set read area by defined names in workbook. For example if workbook has defined name Headers with range Demo1!$B$4:$D$4 then you can read cells by this name

$excel->setReadArea('Values');
$cells = $excel->readCells();

Note that since the value contains the sheet name, this sheet becomes the default sheet.

You can set read area in the sheet

$sheet = $excel->getSheet('Demo1')->setReadArea('Headers');
$cells = $sheet->readCells();

But if you try to use this name on another sheet, you will get an error

$sheet = $excel->getSheet('Demo2')->setReadArea('Headers');
// Exception: Wrong address or range "Values"

If necessary, you can fully control the reading process using the method readSheetCallback() with callback-function

use \avadim\FastExcelReader\Excel;

$excel = Excel::open($file);

/**
 * A callback function that gets the value of each cell 
 *
 * @param int $row Row number
 * @param string $col Column char
 * @param mixed $val Cell value
 *
 * @return bool
 */
function readCellCallback($row, $col, $val)
{
    // Function implementation

    // if the function returns true then data reading is interrupted  
    return false;
}

$excel->readCallback('readCellCallback');

Date Formatter

By default, all datetime values returns as timestamp. But you can change this behavior using dateFormatter()

$excel = Excel::open($file);
$sheet = $excel->sheet()->setReadArea('B5:D7');
$cells = $sheet->readCells();
echo $cells['C5']; // -2205187200

// If argument TRUE is passed, then all dates will be formatted as specified in cell styles
// IMPORTANT! The datetime format depends on the locale
$excel->dateFormatter(true);
$cells = $sheet->readCells();
echo $cells['C5']; // '14.02.1900'

// You can specify date format pattern
$excel->dateFormatter('Y-m-d');
$cells = $sheet->readCells();
echo $cells['C5']; // '1900-02-14'

// set date formatter function
$excel->dateFormatter(fn($value) => gmdate('m/d/Y', $value));
$cells = $sheet->readCells();
echo $cells['C5']; // '02/14/1900'

// returns DateTime instance
$excel->dateFormatter(fn($value) => (new \DateTime())->setTimestamp($value));
$cells = $sheet->readCells();
echo get_class($cells['C5']); // 'DateTime'

// custom manipulations with datetime values
$excel->dateFormatter(function($value, $format, $styleIdx) use($excel) {
    // get Excel format of the cell, e.g. '[$-F400]h:mm:ss\ AM/PM'
    $excelFormat = $excel->getFormatPattern($styleIdx);

    // get format converted for use in php functions date(), gmdate(), etc
    // for example the Excel pattern above would be converted to 'g:i:s A'
    $phpFormat = $excel->getDateFormatPattern($styleIdx);
    
    // and if you need you can get value of numFmtId for this cell
    $style = $excel->getCompleteStyleByIdx($styleIdx, true);
    $numFmtId = $style['format-num-id'];
    
    // do something and write to $result
    $result = gmdate($phpFormat, $value);

    return $result;
});

Images functions

// Returns count images on all sheets
$excel->countImages();

// Returns count images on sheet
$sheet->countImages();

// Returns image list of sheet
$sheet->getImageList();

// Returns image list of specified row
$sheet->getImageListByRow($rowNumber);

// Returns TRUE if the specified cell has an image
$sheet->hasImage($cellAddress);

// Returns mime type of image in the specified cell (or NULL)
$sheet->getImageMimeType($cellAddress);

// Returns inner name of image in the specified cell (or NULL)
$sheet->getImageName($cellAddress);

// Returns an image from the cell as a blob (if exists) or NULL
$sheet->getImageBlob($cellAddress);

// Writes an image from the cell to the specified filename
$sheet->saveImage($cellAddress, $fullFilenamePath);

// Writes an image from the cell to the specified directory
$sheet->saveImageTo($cellAddress, $fullDirectoryPath);

Cell value types

The library tries to determine the types of cell values, and in most cases it does it right. Therefore, you get numeric or string values. Date values are returned as a timestamp by default. But you can change this behavior by setting the date format (see the formatting options for the date() php function).

$excel = Excel::open($file);
$result = $excel->readCells();
print_r($result);

The above example will output:

Array
(
    [B2] => -2205187200
    [B3] => 6614697600
    [B4] => -6845212800
)

$excel = Excel::open($file);
$excel->setDateFormat('Y-m-d');
$result = $excel->readCells();
print_r($result);

The above example will output:

Array
(
    [B2] => '1900-02-14'
    [B3] => '2179-08-12'
    [B4] => '1753-01-31'
)

How to get complete info about the cell style

Usually read functions return just cell values, but you can read the values with styles. In this case, for each cell, not a scalar value will be returned, but an array like ['v' => scalar_value, 's' => style_array, 'f' => formula]

$excel = Excel::open($file);

$sheet = $excel->sheet();

$rows = $sheet->readRowsWithStyles();
$columns = $sheet->readColumnsWithStyles();
$cells = $sheet->readCellsWithStyles();

$cells = $sheet->readCellsWithStyles();

Or you can read styles only (without values)

$cells = $sheet->readCellStyles();
/*
array (
  'format' => 
  array (
    'format-num-id' => 0,
    'format-pattern' => 'General',
  ),
  'font' => 
  array (
    'font-size' => '10',
    'font-name' => 'Arial',
    'font-family' => '2',
    'font-charset' => '1',
  ),
  'fill' => 
  array (
    'fill-pattern' => 'solid',
    'fill-color' => '#9FC63C',
  ),
  'border' => 
  array (
    'border-left-style' => NULL,
    'border-right-style' => NULL,
    'border-top-style' => NULL,
    'border-bottom-style' => NULL,
    'border-diagonal-style' => NULL,
  ),
)
 */
$cells = $sheet->readCellStyles(true);
/*
array (
  'format-num-id' => 0,
  'format-pattern' => 'General',
  'font-size' => '10',
  'font-name' => 'Arial',
  'font-family' => '2',
  'font-charset' => '1',
  'fill-pattern' => 'solid',
  'fill-color' => '#9FC63C',
  'border-left-style' => NULL,
  'border-right-style' => NULL,
  'border-top-style' => NULL,
  'border-bottom-style' => NULL,
  'border-diagonal-style' => NULL,
)
 */
