## What it is
ExcellentExport.js is a client-side JavaScript library that exports HTML tables to Excel (XLSX) or CSV files directly in the browser, with no server required. It supports cell types and formats, merged cells (rowspan/colspan), and RTL options.

## Use cases
- export html table to excel in browser
- client-side csv export from table
- download xlsx file from javascript without server
- export table with merged cells to excel
- format cells as dates or numbers in exported excel
- add excel export button to web page

## When to choose
- you need Excel/CSV export purely client-side with no backend
- you want to export existing HTML tables including merged cells and cell formatting
- you want a small, MIT-licensed drop-in library

## When to avoid
- you need to export data not present in an HTML table
- bundle size matters and 200+ KB for XLSX support is too heavy
- you need server-side or streaming export of very large datasets

- artifact type: library
- maturity: active
