NOTE: this library / tool is a relic from a time when the SheetJS Spreadsheet
Parsing and Writing libraries were separate entities. They have been unified in
the js-xlsx project, xlsx on NPM.
New projects should be using that library directly.
Simple data wrapper that attempts to wrap SheetJS libraries to provide a uniform way to access data from Excel and other spreadsheet files:
- JS-XLSX:
xlsxon NPM - JS-XLS:
xlsjson NPM - JS-HARB:
harbon NPM
Excel files are parsed based on the content (not by extension). For example, CSV files can be renamed to .XLS and excel will do the right thing.

$ npm install -g jvar J = require('j');J.readFile(filename) opens file specified by filename and returns an array
whose first object is the parsing object (XLS or XLSX) and whose second object
is the parsed file.
J.utils has various helpers that expect an array like those from readFile:
| Format | utility function |
|---|---|
| Excel 2007+ XML Formats (XLSX/XLSM) | to_xlsx/to_xlsm |
| Excel 2007+ Binary Format (XLSB BIFF12) | to_xlsb |
| Excel 2.0/2.1 (XLS BIFF2) | to_biff2 |
| Delimiter-Separated Values (CSV/TSV/DSV) | to_csv/to_dsv |
| Data Interchange Format (DIF) | to_dif |
| Symbolic Link (SYLK/SLK) | to_sylk |
| OpenDocument Spreadsheet (ODS) | to_ods |
| Flat XML ODF Spreadsheet (FODS) | to_fods |
| HTML Tables | to_html |
| Markdown Tables | to_md |
| XML Data (XML) | to_xml |
| Ethercalc Record Format (ETH) | to_socialcalc |
| JSON Row Objects | to_json |
| List of Formulae | to_formulae |

Using git textconv, you can use J to generate more meaningful diffs!
One-time configuration (misc/gitdiff.sh):
#!/bin/bash
# Define a sheetjs diff type that uses j
git config --global diff.sheetjs.textconv "j"
# Configure a user .gitattributes file that maps the xls{,x,m} files
touch ~/.gitattributes
cat <<EOF >>~/.gitattributes
*.xls diff=sheetjs
*.xlsb diff=sheetjs
*.xlsm diff=sheetjs
*.xlsx diff=sheetjs
*.XLS diff=sheetjs
*.XLSB diff=sheetjs
*.XLSM diff=sheetjs
*.XLSX diff=sheetjs
EOF
# Set the .gitattributes to be used for all repos on the system:
git config --global core.attributesfile '~/.gitattributes'
If you just want to compare formulae (for example, in a sheet using NOW):
git config --global diff.sheetjs.textconv "j -S"
NOTE: There are some known issues regarding global modules in Windows. The best
bet is to npm install j in your git directory before diffing.
