Node.js Excel Export

node-excel-export is a Node.js module designed for generating `.xlsx` files from JavaScript datasets. It takes an array of objects as input along with a JSON-based report specification, allowing for flexible configuration of column headers, data mapping, and cell styling. The current stable version is 1.4.4. While its release cadence appears to be slow, suggesting a mature and largely feature-complete library, it remains functional for its stated purpose. Key differentiators include its ability to apply rich cell styling, dynamically reformat data using renderer functions, and define complex header rows and cell merges directly from a JavaScript configuration. It abstracts away the complexities of the underlying `xlsx` (js-xlsx) library for common export scenarios, providing a simpler API for generating Excel reports on the server side.
