Embodiments presented herein provide techniques for executing a block-based workflow to perform a planning process for a semiconductor manufacturing environment. The block-based workflow includes a plurality of blocks that specify a set of operations for performing the planning process. One embodiment includes extracting planning data from a spreadsheet application, converting the data from a first schema to a second schema, generating a plan for the semiconductor manufacturing environment, and publishing the plan to the spreadsheet application, based on the plurality of blocks in the block-based workflow.
