Default connectors often fail with larger files, processing records for tens of seconds (or longer). Fortunately, there&#8217;s a solution: a custom Excel script that generates a JSON file and seamlessly integrates with Power Apps and Power Automate. The fast Excel row reading in Power Apps approach I&#8217;ll show you speeds up massive data imports by up to 10 times and allows you to retrieve 30,000 rows in just a few seconds. Sound good? Read on!<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/appser.it\/wp-content\/uploads\/2026\/01\/power_apps_excel_batch_diagram.png\" alt=\"\" class=\"wp-image-504\" srcset=\"https:\/\/appser.it\/wp-content\/uploads\/2026\/01\/power_apps_excel_batch_diagram.png 1024w, https:\/\/appser.it\/wp-content\/uploads\/2026\/01\/power_apps_excel_batch_diagram-300x300.png 300w, https:\/\/appser.it\/wp-content\/uploads\/2026\/01\/power_apps_excel_batch_diagram-150x150.png 150w, https:\/\/appser.it\/wp-content\/uploads\/2026\/01\/power_apps_excel_batch_diagram-768x768.png 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Why is standard Excel data reading so slow?<\/h2>\n\n\n\n<p>The problem is simple: standard Power Apps and Power Automate connectors process data row by row. Transferring individual records, batch limits, and complex queries make bulk imports take a long time and burden the entire application. Especially with files containing thousands of rows, this results in frustrating waiting times, timeouts, and errors.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What&#8217;s the optimal solution?<\/h2>\n\n\n\n<p>The secret lies in an Office Script that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>automatically aggregates selected data from the entire file,<\/li>\n\n\n\n<li>exports it in bulk to JSON format,<\/li>\n\n\n\n<li>returns one ready-made file to Power Apps or Power Automate.<\/li>\n<\/ul>\n\n\n\n<p>Thanks to this, the number of requests sent to Excel drops to virtually zero. A single retrieval is enough and the entire dataset (even hundreds of thousands of records) is immediately available in the application.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How does it work step by step?<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Creating an Office Script in Excel<\/strong><br>You write a script that cleans, sorts, and exports data in the appropriate structure to JSON.<\/li>\n\n\n\n<li><strong>Adding a Power Automate Flow<\/strong><br>Power Automate calls the Excel script from a file stored on SharePoint. In response, you get a ready-made JSON with data.<\/li>\n\n\n\n<li><strong>Integration with Power Apps<\/strong><br>Power Apps calls the Flow from Power Automate. The entire export process takes a few seconds, and the data is available at once in the application, ready for processing.<\/li>\n<\/ol>\n\n\n\n<p>This architecture eliminates typical limitations and provides up to a tenfold speed increase.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">When is it worth implementing?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Are you analyzing large datasets (e.g., customer lists, orders)?<\/li>\n\n\n\n<li>Do you need full automation without manual work?<\/li>\n\n\n\n<li>Do you need rapid prototyping of applications for business data?<\/li>\n\n\n\n<li>Do you want to read thousands or tens of thousands of records in bulk without the risk of timeouts?<\/li>\n<\/ul>\n\n\n\n<p>If the answer is &#8220;yes,&#8221; this technique is perfect for you.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<p>Fast Excel row reading in Power Apps isn&#8217;t just about better performance. It&#8217;s also about stability, reliable integration, and scalability, even for really large files. Using a simple Excel script, you export the entire file with one click, eliminate problems with limits, and drastically reduce the time it takes to deliver data to business applications.<\/p>\n\n\n\n<p><em>Want to implement bulk Excel import in your organization?
