What is an XLTM file?

The XLTM file is a macro-enabled template format introduced with Microsoft Office 2007, based on the Office Open XML (OOXML) architecture. It combines the templating functionality of XLTX with the ability to store Visual Basic for Applications (VBA) macros (contained in a vbaProject.bin part within the ZIP container). This format allows organizations to deploy standardized spreadsheets that include automation scripts, while preventing users from modifying the base template file.

How to open an XLTM file

Microsoft Excel is the primary application for creating and executing XLTM files with full VBA support. While LibreOffice Calc and OpenOffice can open XLTM templates, they may not execute proprietary VBA macros correctly. Mobile versions of Office and web-based viewers typically allow viewing the template structure but disable macro execution for security reasons.

What is a PDF/A file?

PDF/A is an ISO-standardized (ISO 19005) variant of the PDF format designed specifically for long-term digital archiving. It embeds all fonts, color profiles, and metadata directly inside the file and prohibits external dependencies, encryption, and JavaScript, ensuring the document will render identically decades from now regardless of which software or fonts are available on the viewing system. It's widely required for legal, government, and institutional record-keeping.

How to open a PDF/A file

PDF/A files open in any standard PDF viewer, including Adobe Acrobat Reader, Apple Preview, and built-in browser PDF viewers, since the format is fully backward-compatible with regular PDF readers. Dedicated archival software such as Adobe Acrobat Pro can also validate that a file meets PDF/A compliance.
