Read and Write CSV File Format

Possible Usage Scenarios

Microsoft Excel supports many formats like XLS, XLSX, XLSM, XLSB, CSV, etc. Aspose.Cells also supports many of these formats. This article explains how to read and write the excel file having CSV format using Aspose.Cells.

Read and Write CSV File Format

The following sample code loads the source CSV file and reads its cell A1 and then copies its contents to cell C4 and saves it as output CSV file.

Sample Code

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Source directory path
StringPtr dirPath = new String("..\\Data\\LoadingSavingAndConverting\\");

//Output directory path
StringPtr outPath = new String("..\\Data\\Output\\");

//Path of input csv file
StringPtr srcReadWriteCSV = dirPath->StringAppend(new String(L"srcReadWriteCSV.csv"));

//Path of output csv file
StringPtr outReadWriteCSV = outPath->StringAppend(new String(L"outReadWriteCSV.csv"));

//Read source csv file
intrusive_ptr<IWorkbook> wb = Factory::CreateIWorkbook(srcReadWriteCSV);

//Access first worksheet
intrusive_ptr<IWorksheet> ws = wb->GetIWorksheets()->GetObjectByIndex(0);

//Access cell A1
intrusive_ptr<ICell> cell = ws->GetICells()->GetObjectByIndex(new String("A1"));

//Get the string value of cell A1
StringPtr strVal = cell->GetStringValue();

//Print the string value of cell A1
StringPtr cellValue = new String("Cell Value: ");
Console::WriteLine(cellValue->StringAppend(strVal));

//Access cell C4
cell = ws->GetICells()->GetObjectByIndex(new String("C4"));

//Put the string value of cell A1 into C4
intrusive_ptr<String> strValPtr = new String(strVal);
cell->PutValue(strValPtr);

//Save the workbook in csv format
wb->Save(outReadWriteCSV, SaveFormat_CSV);
