DEV post: edit DOCX via a change list, not a full rewrite

On 2026-11-12 at 09:56, the AI section of DEV Community published an article titled "Let AI edit DOCX without breaking the formatting: produce a change list first, then edit in place." The piece asks how you can let AI edit an existing DOCX file without breaking the formatting, and answers with a simple workflow. The first rule is: never ask the model to produce a new Word file. Instead, ask it for a short list of changes, each tied to an exact place in the original, such as a paragraph, a table cell, or a placeholder. Those changes are then applied to the original file with a library that edits in place, so the original structure is preserved. Before the file is saved or sent, a person is shown a before-and-after view and confirms the edits. The article notes that this exact question was asked in a recent thread on r/AI_Agents, where a user was struggling with an agent that broke the formatting while updating a clause in a document, including several table cells. This is the only report received so far. The article presents the approach and the underlying reasoning, but it does not cover a specific tool, an implementation walkthrough, or performance results, so the discussion currently stands at the proposal stage.
