# [:green_book: SheetJS js-xlsx](http://sheetjs.com)
Parser and writer for various spreadsheet formats. Pure-JS cleanroom
implementation from official specifications, related documents, and test files.
Emphasis on parsing and writing robustness, cross-format feature compatibility
with a unified JS representation, and ES3/ES5 browser compatibility back to IE6.
[**In-Browser Demo**](http://oss.sheetjs.com/js-xlsx)
This is the community version. We also offer a pro version with performance
enhancements and additional features by request.
