How to open .DOCM files on iOS

To open .DOCM files on iOS, in the Files app, tap the .DOCM file and try opening it in Microsoft Word for iOS (if installed); otherwise share it to a compatible document app or open it on a desktop for full support.

Step-by-step instructions

  1. In the Files app, tap the .DOCM file and try opening it in Microsoft Word for iOS (if installed); otherwise share it to a compatible document app or open it on a desktop for full support.

Alternative methods

  • Open .DOCM in a browser-based viewer if desktop apps fail.
  • Try opening .DOCM on iOS with a secondary app to rule out app-specific issues.
  • Convert .DOCM only with trusted tools when direct opening is not possible.

Common issues

The file opens, but macros are disabled or don’t run

.DOCM can contain VBA macros, and many apps intentionally block macros for safety or don’t implement macro execution.

  1. If you need the macro features, open the file in Microsoft Word and review the macro/security prompt before enabling anything.
  2. If you’re using a viewer or non-Word editor, expect macros to be blocked or ignored; use Word for full macro behavior.

“Can’t open file” or “File is corrupted” error

.DOCM is an OOXML package; partial downloads, email filtering, or file corruption can prevent the ZIP-based container from being read.

  1. Re-download the file or ask the sender to re-send it (preferably via a reliable transfer method).
  2. Try opening it in Microsoft Word on another computer to rule out an app-specific issue.

Formatting looks wrong or content is missing

.DOCM relies on WordprocessingML features; some applications have incomplete compatibility with Word’s layout, fonts, and embedded objects.

  1. Open the document in Microsoft Word for the most faithful rendering.
  2. If you must use another app, ask the sender for a .PDF for viewing or a .DOCX copy if macros are not required.

The file opens, but it’s flagged as unsafe or prompts appear every time

Because .DOCM can contain active macro code, Office apps may open it in a restricted mode or keep warning you depending on trust settings.

  1. Do not enable macros unless you trust the sender and understand what the macro is supposed to do.
  2. If it’s a legitimate internal workflow document, use your organization’s approved trust mechanisms and policies rather than disabling protections globally.

Security note

.DOCM files can contain VBA macros (active code). Only enable macros if you trust the source and expected behavior of the document.
