Extract text from ProntoDoc Excel documents (PDER)
To convert PDER documents to another format, you need Microsoft Excel or other Spreadsheet software.
To convert other file formats to the "Excel Add-in Document" file type, you need software like Microsoft Excel or a similar tool.
The .PDER file is a ProntoDoc for Excel Conventional Document originally developed by Step Function. Enterprise organizations use these files primarily for automated document generation and dynamic reporting within spreadsheet environments.
To properly open or edit a .PDER file, you must use Microsoft Excel equipped with the licensed ProntoDoc add-in.
Users frequently need to convert this file because the .PDER format strictly limits data accessibility. It is a proprietary format that enforces vendor lock-in and requires specialized software to read. You cannot open these files on mobile devices, view them in standard web browsers, or import them into alternatives like Google Sheets or LibreOffice. This creates major workflow bottlenecks when distributing financial reports or templates to external stakeholders.
The most practical target formats for conversion are XLSX to retain standard spreadsheet functionality, or PDF for secure, fixed-layout viewing. Be aware that converting away from .PDER will permanently break the dynamic database links and custom ProntoDoc automation scripts, leaving only the static text and numerical data.
This file format is exceptionally difficult to open or convert because it is closed and proprietary. Often, only the original ProntoDoc software can properly read or export the structured data.
