SheetJS Community Edition is a JavaScript library that reads, writes, and converts spreadsheet files (XLSX, XLS, CSV, ODS, and more) with a unified interface across browsers, Node.js, Deno, Bun, and mobile runtimes. It is the open-source core of the SheetJS toolkit, focused on extracting data from and generating spreadsheets compatible with both legacy and modern software.
Use cases
- read xlsx files in javascript or nodejs
- convert csv to excel and excel to csv
- export data to an xlsx spreadsheet from a web app
- parse excel spreadsheets into for a database import
- generate downloadable spreadsheet reports in the browser
- convert between spreadsheet formats like xls, xlsx, ods, and html tables
- extract tabular data from uploaded excel files in a react, vue, or angular app
When to choose
- You need to read or write Excel, CSV, or ODS files in JavaScript across browsers, Node, Deno, or Bun with one consistent API
- You need a battle-tested, dependency-light spreadsheet parser with very broad legacy and modern format support
- You need to move tabular data between spreadsheets and JavaScript objects or JSON in a data import/export pipeline
When to avoid
- You need advanced styling, images, charts, PivotTables, or full formula evaluation, which are SheetJS Pro features beyond the Community Edition
- You need a full interactive spreadsheet grid or editor UI rather than a data processing library
- You need streaming, low-memory processing of extremely large workbooks, which may require a specialized streaming parser
