Versions:
乐启office工具箱 is a lightweight Windows utility released by GitHub user “leqi-tec” that streamlines the creation of Microsoft Office documents by merging data with reusable templates. Positioned in the Office productivity category, the program accepts a folder of Word, Excel or PowerPoint templates together with a structured data source—CSV, JSON or simple key-value pairs—and produces finished files in the corresponding Office format without manual copy-paste work. Typical use cases include generating personalized offer letters, invoices, certificates or marketing decks for hundreds of recipients at once, preparing semester reports for every student from a single grade sheet, or assembling localized product datasheets from a master template and multilingual strings. Version 0.0.1, the only release published so far, exposes a command-line interface plus a minimal GUI for selecting template directory, data file and output location; it automatically maps column headers to template placeholders, preserves original formatting and embedded images, and can optionally convert results to PDF. Written in C# and licensed under MIT, the 18 MB package runs on Windows 10/11 with .NET 6 runtime and requires no additional Office COM libraries because it employs the Open XML SDK for reading and writing docx/xlsx/pptx files. The project repository documents sample scripts that loop through customer lists, insert QR codes or bar-codes, and rename outputs according to employee ID or order number. Although still at an early stage, the tool already supports nested placeholders, conditional sections and image substitution tokens, making it suitable for low-code automation inside larger workflows. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
