How to open a PLN file on Android: step-by-step guide for all formats

Files with the extension .pln are most often associated with documents PlanMaker —a spreadsheet editor from the package SoftMaker Office. However, on Android such files can cause difficulties: standard applications do not recognize them, and specialized software is not always available in Google Play. In this article, we will look at all working methods for opening PLN on a smartphone, including workarounds for outdated versions of Android and alternative apps.

It is important to understand that the format .pln has two types: classic PlanMaker Document (analog .xls/.xlsx) and PlanMaker Mobile Template (templates for the mobile version). The methods for opening them are different, so we will consider both cases separately. If you are not sure which file you have, first try the universal solutions from the first section.

Before you begin, check:

• 📱 Android version (in Settings → About phone): more options are available on Android 10 and later.
• 📄 File size: if PLN weighs more than 50 MB, online services may not cope.
• 🔒 A password: protected files will require original software from SoftMaker.

1. Official solution: PlanMaker Mobile for Android

Polaris Office	⚠️ View only	❌ No (paid editing)	Distorts formatting in complex files
WPS Office	❌ No (only through conversion)	✅ Yes	Requires preliminary conversion to XLSX
