CSV format

Loading CSV format

Workbook vs. Worksheet

Both workbook and worksheet have the ability to load data from CSV format. Workbook will load the content from a CSV format and remove all other existed worksheets; Worksheet loads content from CSV format only fill itself.

Loading CSV into workbook

To load a CSV format into a workbook, use the Load method and pass the file format as CSV:

grid.Load("C:\\mypath\\data.csv", IO.FileFormat.CSV);

Loading CSV into worksheet

To load a CSV format into worksheet, use the following methods:

// load from stream
sheet.LoadCSV(Stream s);

// load from file
sheet.LoadCSV(string path);

// load from stream and convert string by specified encoding
sheet.LoadCSV(Stream s, Encoding encoding);

// load from path and convert string by specified encoding
sheet.LoadCSV(string path, Encoding encoding);

// load from stream by specifying autoSpread, bufferLines and encoding
sheet.LoadCSV(Stream s, bool autoSpread, int bufferLines, Encoding encoding);

For example: load from file by using Japanese encoding “shift-jis”

sheet.LoadCSV(@"G:\ReoGrid\Samples\13TOKYO.CSV",
  Encoding.GetEncoding("shift-jis"));

Sample after loading:

Auto Spread

By default, ReoGrid will add rows and columns automatically in order to expending the spreadsheet to load more data, to disable this behavior, set the autoSpread argument to false.

Export as CSV Format

To save worksheet as CSV format, use the following methods:

var sheet = grid.CurrentWorksheet;

// export to file
sheet.ExportAsCSV(string path);

// export to stream
sheet.ExportAsCSV(Stream s);

Export only specified range

It’s possible to export a specified range rather than entire worksheet, use the overload methods of ExportAsCSV and specifying the the grid or row range.

// export from second row, this is useful if do not 
// want export the header that is the first row
sheet.ExportAsCSV("C:\\mypath\\file.csv", 1);

// export a range
sheet.ExportAsCSV("C:\\mypath\\file.csv", "A1:H30");

Export by specified encoding

Sometime it is necessary to specify the encoding if worksheet contains Unicode text, to specify the encoding, use the third argument of these methods:

sheet.ExportAsCSV("C:\\mypath\\file.csv", "A1:H30", 
  Encoding.GetEncoding("shift-jis"));
