 luban相较于常规的excel导表工具有以下核心优势：
 - 增强了excel格式。可以比较简洁地excel配置**任意复杂**的数据，像子结构、结构列表，以及更复杂的深层次的嵌套结构都能直接解析处理。
 - 完备的类型系统和多原始数据支持（xml、json、lua、yaml），可以轻松表达和解析**任意复杂**的数据。意味着传统excel导表工具无法处理的技能、行为树、副本等等复杂配置，luban也能够统一处理了，彻底将程序从复杂的配置解析中解放出来。
-- 完善的工作流支持。如id的外键引用检查;资源合法性检查;灵活的数据源定义（拆表或者多表合一）;灵活的分组导出机制；多种本地化支持;生成极快（日常迭代300ms以内）；Excel2TextDiff工具方便diff查看excel文件的版本间差异；

 - **LubanAssistant Excel插件**。支持把json、lua、xml等文本格式的配置数据加载到excel中，批量编辑处理，最后再保存回原文件，较好地解决大型项目中多人合作数据编辑冲突合并的问题，较好解决在编辑器中制作的配置难以在excel中批量修改的问题。
 - 支持自定义代码与数据模板。强大的数据表达能力使得绝大多数项目的配置格式往往是luban的子集，因而有较低的项目迁移成本，利用模板重新适配代码和数据生成后，即使是研发已久或者上线项目也能从luban强大的数据处理能力中受益。
