# WRL projects team costing tool This spreadsheet is used to estimate the costs when preparing proposals for the WRL projects team. ## Workflow `xlsx` is a binary format, and is not well-suited for version control. When making changes to the macro modules within the workbook, please ensure the changes are mirrored in the vbs text files (e.g. `costing-tool-module-1.vbs`) before each commit. This makes it much easier to view the changes using `git diff`.
