Spreadsheet Decoder

Build Status Coverage Status Pub version

Spreadsheet Decoder is a library for decoding spreadsheets for ODS and XLSX files.


On server-side

import 'dart:io';
import 'package:spreadsheet_decoder/spreadsheet_decoder.dart';

main() {
  var bytes = new File.fromUri(fullUri).readAsBytesSync();
  var decoder = new SpreadsheetDecoder.decodeBytes(bytes);
  var table = decoder.tables['Sheet1'];
  var values = table.rows[0];

On client-side

import 'dart:html';
import 'package:spreadsheet_decoder/spreadsheet_decoder.dart';

main() {
  var reader = new FileReader();
  reader.onLoadEnd.listen((event) {
    var decoder = new SpreadsheetDecoder.decodeBytes(reader.result);
    var table = decoder.tables['Sheet1'];
    var values = table.rows[0];

Features not yet supported

This implementation doesn't support following features:

  • annotations
  • spanned rows
  • spanned columns
  • hidden rows (visible in resulting tables)
  • hidden columns (visible in resulting tables)

For XLSX format, this implementation only supports native Excel format for date, time and boolean type conversion. In other words, custom format for date, time, boolean aren't supported and then file exported from LibreOffice as well.


Fix string parsing on xlsx file Fix sheet target selection


Fix misalignment of decoded value with empty columns


Output typed data (number, string, date, time, boolean)


Add XLSX decoder


Add ODS decoder

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.
