How the PHP array becomes XLSX

A small recursive parser walks the array() or [] structure token by token, honoring 'key' => value pairs, nested arrays, quoted strings with escapes, numbers, booleans and null. Each top-level associative array becomes one row, and the XLSX serializer then renders those rows in the target format with correct escaping for XLSX.

Tips for the spreadsheet output

Use the preview to sanity-check headers before downloading, especially after converting from PHP array, where column order follows first appearance. The .xlsx opens in Excel, Google Sheets and LibreOffice, so it is a handy handoff format when colleagues need to eyeball or edit the converted data.

PHP array to XLSX FAQs

What PHP array styles can I paste?
Both array(...) and [...] syntax work, with 'key' => value pairs, nested arrays, quoted strings, numbers, booleans and null. You can include the opening <?php tag and a $variable = assignment, they are stripped automatically. A list of associative arrays converts cleanest; plain lists become single-column rows.
How do I get the .xlsx file?
Press Convert, check the preview in the output box, then press Download .xlsx. The workbook has one sheet named data with your headers in row 1. It opens in Excel, Google Sheets and LibreOffice with types preserved.
What happens to nested PHP arrays?
Nested arrays are preserved as nested structures in the output where the format allows it (JSON, PHP, XML), and rendered as compact JSON text in flat formats like XLSX. Scalar lists become rows with a single value column.
Is there a size limit for PHP array input?
No hard limit, but everything runs in your browser tab, so tens of thousands of rows convert in seconds while millions of rows may slow the page. For very large PHP array files, split them into smaller chunks and convert each separately.
Is my PHP array data private, and who uses this?
Yes. The conversion runs 100% in your browser with the SheetJS library loaded from CDN; nothing is uploaded to any server. Developers, analysts and DBAs use it to move PHP array data into XLSX for migrations, reports and config work without installing anything.
