A Node.js library for parsing and building Excel (xlsx/xls) files, built as a convenient wrapper around SheetJS. It offers a simple API to read spreadsheets from files or buffers and generate Excel files from arrays of data, with options for column widths and merged cells.

Use cases

• parse xlsx files in nodejs
• generate excel spreadsheets from data
• convert excel sheets to javascript arrays
• export data to xlsx with custom column widths
• read excel files from a buffer
• create spreadsheets with merged cells

When to choose

• you need a simple, typed API to read or write Excel files in Node.js
• you want a thin convenience layer over SheetJS for common xlsx tasks
• you need to build spreadsheets with column widths or merged ranges

When to avoid

• you need advanced Excel features like formulas, styling, or charts
• you are not in a Node.js environment (e.g. browser or Python)
• you need streaming processing of very large spreadsheets
