Data Grids and Tables
Various JavaScript UI components provide a more interactive editing experience. Most are able to interchange with arrays of arrays or arrays of data objects. This demo focuses on a few open source data grids.
SheetJS Pro offers additional features like styling and images. The UI tools typically support many of these advanced features.
To eliminate any confusion, the live examples linked from this page demonstrate SheetJS Community Edition data interchange.
Managed Lifecycle​
Many UI components tend to manage the entire lifecycle, providing methods to import and export data.
The sheet_to_json utility function generates arrays of objects, which is
suitable for a number of libraries. When more advanced shapes are needed,
it is easier to process an array of arrays.
x-spreadsheet​
With a familiar UI, x-spreadsheet is an excellent choice for a modern editor.

Canvas Datagrid​
After extensive testing, canvas-datagrid stood out as a high-performance grid
with a straightforward API.

Tabulator​
Tabulator includes deep support through a special Export button. It handles the SheetJS operations internally.

Angular UI Grid​
This UI Grid is for AngularJS, not the modern Angular. New projects should not use AngularJS. This demo is included for legacy applications.
The AngularJS demo covers more general strategies.

Notes (click to show)
The library does not provide any way to modify the import button, so the demo includes a simple directive for a File Input HTML element. It also includes a sample service for export which adds an item to the export menu.
The demo SheetJSImportDirective follows the prescription from the README for
File input controls using readAsArrayBuffer, converting to a suitable
representation and updating the scope.
SheetJSExportService exposes export functions for XLSB and XLSX. Other
file formats can be exported by changing the bookType variable. It grabs
values from the grid, builds an array of arrays, generates a workbook and forces
a download. By setting the filename and sheetname options in the ui-grid
options, the output can be controlled.
Framework Lifecycle​
For modern frameworks like React, data grids tend to follow the framework state
and idioms. The same sheet_to_json and json_to_sheet / aoa_to_sheet
methods are used, but they pull from a shared state object that can be mutated
with other buttons and components on the page.

Standard HTML Tables​
Many UI components present styled HTML tables. Data can be extracted from the tables given a reference to the underlying TABLE element:
function export_html_table(table) {
const wb = XLSX.utils.table_to_book(table);
XLSX.writeFile(wb, "HTMLTable.xlsx");
} // yes, it's that easy!
SheetJS CE is focused on data preservation and will extract values from tables.
SheetJS Pro offers styling support when reading from TABLE elements and when writing to XLSX and other spreadsheet formats.
Fixed Tables​
When the page has a raw HTML table, the easiest solution is to attach an id:
<script src="https://cdn.sheetjs.com/xlsx-0.20.3/package/dist/shim.min.js"></script>
<script src="https://cdn.sheetjs.com/xlsx-0.20.3/package/dist/xlsx.full.min.js"></script>
<!-- table with id `xport` -->
<table id="xport"><tr><td>SheetJS</td></tr></table>
<script>
/* as long as this script appears after the table, it will be visible */
var tbl = document.getElementById("xport");
const wb = XLSX.utils.table_to_book(tbl);
XLSX.writeFile(wb, "HTMLTable.xlsx");
</script>
When programmatically constructing the table in the browser, retain a reference:
/* assemble table */
var tbl = document.createElement("TABLE");
tbl.insertRow(0).insertCell(0).innerHTML = "SheetJS";
/* add to document body */
document.body.appendChild(tbl);
/* generate workbook and export */
const wb = XLSX.utils.table_to_book(tbl);
XLSX.writeFile(wb, "HTMLFlicker.xlsx");
/* remove from document body */
document.body.removeChild(tbl);
