LogicalDOC Office Add-in 4.2.0 is here

Built for LogicalDOC 9.3.1, with API key authentication, an editable Revision field and a refreshed ribbon for Word, Excel, PowerPoint, Visio and Project.

We are pleased to announce the release of LogicalDOC Office Add-in 4.2.0, the latest version of the tool that brings your document archive directly inside Microsoft Office.

LogicalDOC Office Add-in for Windows lets you work on documents stored in LogicalDOC from within Word, Excel, PowerPoint, Visio and Microsoft Project (Office 2016–2024 and Microsoft 365). You can open, edit and save documents back to the archive without ever switching to the browser. Check-out, check-in and versioning are handled automatically in the background.

What's new in 4.2.0

  • Built for LogicalDOC 9.3.1. The add-in is aligned with the latest LogicalDOC API and requires LogicalDOC 9.3.1.
  • More reliable full-text search. We fixed an issue that could interrupt content searches when the server returned malformed XML.

Also included: the improvements introduced in 4.1

If you are upgrading from the 4.0 series, version 4.2.0 also brings everything introduced in 4.1:

  • API key authentication. The add-in now connects to LogicalDOC exclusively through a personal API key instead of a username and password. Generating one takes less than a minute: in LogicalDOC, go to Account > Security > API Keys and create a new key. Then paste it into the API Key field in the add-in's Settings panel on the LogicalDOC ribbon tab. Keys can be created and revoked at any time, which gives you better control over the access granted to each client.
  • Session-independent operation. Requests no longer depend on a session ID, which makes the connection to the server more robust.
  • Editable Revision field. You can now view and edit the document's Revision field directly from Office, without opening LogicalDOC in the browser.
  • A refreshed ribbon. New, sharper icons give the LogicalDOC tab a cleaner look on modern high-resolution displays.

See it in action

Watch the full demo to see how the Office Add-in connects Microsoft Word to LogicalDOC: opening documents from the archive, editing them with automatic versioning, inserting images from the repository, comparing versions, exporting to PDF and editing metadata.

Before you upgrade

  • Make sure your server is running LogicalDOC 9.3.1. This version is required by the add-in.
  • After installing the add-in, generate your API key and enter it in the add-in settings. Previous username/password configurations are no longer used. Step-by-step instructions are available in the Configure Office Add-in guide.

LogicalDOC Office Add-in 4.2.0 requires LogicalDOC 9.3.1 and Microsoft Office 2016–2024 or Microsoft 365 on Windows.
