CSV Sheet Build Status

Dart based CSV parser which for reading and accessing CSV Files as spreadsheets (as opposed to lists). Currently the library is read-only and does not support writing to a CSV file. This functionality may come in the future.

The aim of CsvSheet is to make handling CSV Data more like dealing directly with a spreadsheet than with Lists or Arrays. As such the cells are all 1-base indexed as opposed to 0-based like a List. Optionally if a header row is passed you may use that to index the columns. Finally another important reminder is that unlike lists, when referencing cells in the CsvSheet you index by column first then row, just as you would a spreadsheet. More details found below and in the API Documentation.

The Library is available for use on either client or server side applications. It does not currently rely on any other external packages.


Add this line to your pubspec.yaml file:

  csv_sheet: any

Then run pub get to download and link the package.

Basic Usage

First you will need to import the package into your application. Then create a CsvSheet object passing in the CSV data.

import 'package:csv_sheet/csv_sheet.dart';
// ...
var sheet = new CsvSheet(data);

You can optionally pass headerRow if your CSV data contains header information

var sheet = new CsvSheet(data, headerRow: true);

You may also optionally specify field and row separators if you are using separators such as tabs for field sepators or the file contains Windows carriage returns \r\n.

var sheet = new CsvSheet(data, headerRow: true, fieldSep: '\t', lineSep: '\r\n');

CsvSheet will automatically truncate any extra lines from the input, so long as they do not contain the field separators contained within the rest of the data.

Assuming the following spreadsheet, we'll look at how we can access the contents of the cells.

 Sample Spreadsheet
     1    2    3
1 |  1 |  2 |  3 |
2 |  4 |  5 |  6 |
3 |  7 |  8 |  9 |

If this was a normal List and we wanted to access the values stored in col2 row 3, we would reference it as list[3][1] == 8 (assuming headers were also stored in the list). However with CsvSheet to access the same value, we would do so like this:

var value = sheet[2][3];
// Or alternatively:
var value = sheet['col2'][3];
