Worked on improving documentation workflows for the EPPlusSoftware/EPPlus repository by addressing issues with configuration previews in Readme files. Focused on enabling support for JSONC, which allows comments within JSON configuration examples, the work involved changing the preview language from JSON to JSONC to prevent errors when comments were present. This adjustment enhanced the accuracy and usability of documentation for developers referencing configuration samples. The solution was implemented using Markdown for documentation and involved a targeted bug fix rather than feature development. The approach demonstrated attention to detail in documentation practices and improved the developer experience for EPPlus users.
