It walks through creating an Excel sheet with defined names, loading it with PHPExcel's Excel2007 reader, passing form input into named cells, and retrieving calculated values like total price and discount to display on a web page. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I use an existing Excel spreadsheet's pricing formulas in a PHP web application without duplicating the logic? Load the spreadsheet with PHPExcel's Excel2007 reader, assign input values to named cells using setCellValue, then read back calculated results with getCalculatedValue. Define named ranges in Excel (like totalPrice or grandTotal) matching form field names, so form data from $_REQUEST maps directly to spreadsheet cells and the workbook's own formulas compute the output values. _Developers syncing app logic with spreadsheets can track PHP tooling changes like this on daily.dev._ ## Similar posts on daily.dev - [Formula Length](https://daily.dev/posts/formula-length-arflqz5um) · The Daily WTF · 0 upvotes · 0 comments - [Learn Excel Formulas and Functions](https://daily.dev/posts/learn-excel-formulas-and-functions-tkwwefb3a) · freeCodeCamp · 0 upvotes · 0 comments - [Advanced Excel‑Style Data Analysis with React Spreadsheet Formulas](https://daily.dev/posts/advanced-excel-style-data-analysis-with-react-spreadsheet-formulas-gdty5mgb4) · Syncfusion · 0 upvotes · 0 comments --- Tags: [#php](https://daily.dev/tags/php) [View this post on daily.dev](https://daily.dev/posts/reuse-excel-business-logic-with-phpexcel-abwhmari7) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Reuse Excel business logic with PHPExcel","url":"https://daily.dev/posts/reuse-excel-business-logic-with-phpexcel-abwhmari7","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/reuse-excel-business-logic-with-phpexcel-abwhmari7"},"datePublished":"2026-10-04T13:05:07.467Z","dateModified":"2026-10-04T13:09:17.102Z","description":"A tutorial demonstrates how to reuse Excel-based business logic (such as pricing formulas) inside a PHP web application using the PHPExcel library, avoiding...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c5f1132590baf6336e32f9bc878b9315?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c5f1132590baf6336e32f9bc878b9315?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Maarten Balliauw","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Maarten Balliauw","logo":"https://media.daily.dev/image/upload/s--rOTg3VYO--/f_auto,q_auto/v1791119043/logos/maartenballiauw?_a=BAMAMicg0","url":"https://daily.dev/sources/maartenballiauw"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/reuse-excel-business-logic-with-phpexcel-abwhmari7","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"php","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Maarten Balliauw","item":"https://daily.dev/sources/maartenballiauw"},{"@type":"ListItem","position":3,"name":"Reuse Excel business logic with PHPExcel"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/reuse-excel-business-logic-with-phpexcel-abwhmari7#faq","mainEntity":[{"@type":"Question","name":"How can I use an existing Excel spreadsheet's pricing formulas in a PHP web application without duplicating the logic?","acceptedAnswer":{"@type":"Answer","text":"Load the spreadsheet with PHPExcel's Excel2007 reader, assign input values to named cells using setCellValue, then read back calculated results with getCalculatedValue.
