# xlsx
Currently a parser for XLSX and XLSM files. Cleanroom implementation from the
ISO 29500 Office Open XML specifications.
If you need something that is not currently supported, file an issue and attach a sample file. I will get to it :)
ISO 29500 Office Open XML specifications and related documents.
## Installation
@ -13,9 +11,53 @@ In node:
In the browser:
<!-- JSZip must be included before xlsx.js -->
<script lang="javascript" src="/path/to/jszip.js"></script>
<script lang="javascript" src="/path/to/xlsx.js"></script>
## Usage
The node version installs a binary `xlsx2csv` which can read XLSX/XLSM files and output the contents in various formats. The source is available at `xlsx2csv.njs` in the bin directory.
See <http://oss.sheetjs.com/js-xlsx/> for a browser example.
Note that older versions of IE does not support HTML5 File API, so the base64 mode is provided for testing. On OSX you can get the base64 encoding by running:
$ <target_file.xlsx base64 | pbcopy # the pbcopy puts the content in the clipboard
Simple usage (walks through every cell of every sheet and dumps the values):
var XLSX = require('xlsx')
var xlsx = XLSX.readFile('test.xlsx');
var sheet_name_list = xlsx.SheetNames;
xlsx.SheetNames.forEach(function(y) {
for (z in xlsx.Sheets[y]) {
if(z[0] === '!') continue;
console.log(y + "!" + z + "=" + JSON.stringify(xlsx.Sheets[y][z].v));
}
});
Some helper functions in `XLSX.utils` generate different views of the sheets:
- `XLSX.utils.sheet_to_csv` generates CSV
- `XLSX.utils.sheet_to_row_object_array` interprets sheets as tables with a header column and generates an array of objects
- `XLSX.utils.get_formulae` generates a list of formulae
## Notes
`.SheetNames` is an ordered list of the sheets in the workbook
`.Sheets[sheetname]` returns a data structure representing the sheet. Each key
that does not start with `!` corresponds to a cell (using `A-1` notation).
`.Sheets[sheetname][address].v` returns the value of the specified cell and `.Sheets[sheetname][address].t` returns the type of the cell (constrained to the enumeration `ST_CellType` as documented in page 4215 of ISO/IEC 29500-1:2012(E) )
For more details:
- `bin/xlsx2csv.njs` is a tool for node
- `index.html` is the live demo
- `bits/90_utils.js` contains the logic for generating CSV and JSON from sheets
## Tested Environments
- Node 0.8.14, 0.10.1
