-PHPExcel is no longer maintained, and is not PHP8 compatible.
+# Problem

-Propose we move to PHPSpreadsheet
+PHPExcel is no longer maintained, and is not PHP8 compatible (https://github.com/PHPOffice/PHPExcel).
+
+# Proposal
+
+Propose we move to using PHPSpreadsheet (https://github.com/PHPOffice/PhpSpreadsheet). PHPSpreadsheet is the successor to PHPExcel, so the transition is relatively easy, with just a few function name changes.
+
+# Advantages
+
+As well as maintaining PHP8 compatibility, PHPSpreadsheet has the facility to save spreadsheets in other formats, not just Excel, allowing us to save the spreadsheet in Excel format (*.xlsx), or Open document format (*.ods). As we are an open source project I feel more comfortable offering an open format as well as a proprietary one.
+
+# Implementation
+
+We currently only use PHPExcel in two scripts, PcAnalysis.php and PcTabExpensesList.php.
