Read and write simple Excel and CSV files

Latest Version on Packagist Build Status StyleCI Quality Score Total Downloads

This package allows you to easily read and write simple Excel and CSV files. Behind the scenes generators are used to ensure low memory usage, even when working with large files.

Here's an example on how to read an Excel or CSV.

SimpleExcelReader::create($pathToFile)->getRows()
   ->each(function(array $rowProperties) {
        // process the row
    });

If $pathToFile ends with .csv a CSV file is assumed. If it ends with .xlsx, an Excel file is assumed.

Installation

You can install the package via composer:

composer require spatie/simple-excel

Usage

Reading a CSV

Imagine you have a CSV with this content.

email,first_name
john@example.com,john
jane@example.com,jane
// $rows is an instance of Illuminate\Support\LazyCollection
$rows = SimpleExcelReader::create($pathToCsv)->getRows();

$rows->each(function(array $rowProperties) {
   // in the first pass $rowProperties will contain
   // ['email' => 'john@example', 'first_name' => 'john']
});

Reading an Excel file

Reading an Excel file is identical to reading a CSV file. Just make sure that the path given to the create method of SimpleExcelReader ends with xlsx.

Working with LazyCollections

getRows will return an instance of Illuminate\Support\LazyCollection. This class is part of the Laravel framework. Behind the scenes generators are used, so memory usage will be low, even for large files.

You'll find a list of methods you can use on a LazyCollection in the Laravel documentation.

Here's a quick, silly example where we only want to process rows that have a first_name that contains more than 5 characters.

SimpleExcelReader::create($pathToCsv)->getRows()
    ->filter(function(array $rowProperties) {
       return strlen($rowProperties['first_name']) > 5
    })
    ->each(function(array $rowProperties) {
        // processing rows
    });

Reading a file without titles

If the file you are reading does not contain a title row, then you should use the noHeaderRow() method.

// $rows is an instance of Illuminate\Support\LazyCollection
$rows = SimpleExcelReader::create($pathToCsv)
    ->noHeaderRow()
    ->getRows()
    ->each(function(array $rowProperties) {
       // in the first pass $rowProperties will contain
       // [0 => 'john@example', 1 => 'john']
});

Manually working with the reader object

Under the hood this package uses the box/spout package. You can get to the underlying reader that implements \Box\Spout\Reader\ReaderInterface by calling the getReader method.

$reader = SimpleExcelReader::create($pathToCsv)->getReader();

Writing files

Here's how you can write a CSV file:

$writer = SimpleExcelWriter::create($pathToCsv)
     ->addRow([
        'first_name' => 'John',
        'last_name' => 'Doe',
    ])
    ->addRow([
        'first_name' => 'Jane',
        'last_name' => 'Doe',
    ]);

The file at pathToCsv will contain:

first_name,last_name
John,Doe
Jane,Doe

Writing an Excel file

Writing an Excel file is identical to writing a csv. Just make sure that the path given to the create method of SimpleExcelWriter ends with xlsx.

Writing a file without titles

If the file you are writing should not have a title row added automatically, then you should use the noHeaderRow() method.

$writer = SimpleExcelWriter::create($pathToCsv)
    ->noHeaderRow()
    ->addRow([
        'first_name' => 'Jane',
        'last_name' => 'Doe',
    ]);
});

This will output:

Jane,Doe

Adding layout

Under the hood this package uses the box/spout package. That package contains a StyleBuilder that you can use to format rows. Styles can only be used on excel documents.

use Box\Spout\Writer\Common\Creator\Style\StyleBuilder;
use Box\Spout\Common\Entity\Style\Color;

$style = (new StyleBuilder())
   ->setFontBold()
   ->setFontSize(15)
   ->setFontColor(Color::BLUE)
   ->setShouldWrapText()
   ->setBackgroundColor(Color::YELLOW)
   ->build();

$writer->addRow(['values, 'of', 'the', 'row'], $style)

For more information on styles head over to the Spout docs.

Using an alternative delimiter

By default the SimpleExcelReader will assume that the delimiter is a ,.

This is how you can use an alternative delimiter:

SimpleExcelWriter::create($pathToCsv)->useDelimiter(';');

Getting the number of rows written

You can get the number of rows that are written. This number includes the automatically added header row.

$writerWithAutomaticHeader = SimpleExcelWriter::create($this->pathToCsv)
    ->addRow([
        'first_name' => 'John',
        'last_name' => 'Doe',
    ]);

$writerWithoutAutomaticHeader->getNumberOfRows() // returns 2

Manually working with the writer object

Under the hood this package uses the box/spout package. You can get to the underlying writer that implements \Box\Spout\Reader\WriterInterface by calling the getWriter method.

$writer = SimpleExcelWriter::create($pathToCsv)->getWriter();
