Convert CSV to JSON with Node.js via C++

Convert CSV to JSON

Aspose.Cells supports converting CSV to JSON. For this, the API provides ExportRangeToJsonOptions and JsonUtility classes. The ExportRangeToJsonOptions class provides the options for exporting range to JSON. The ExportRangeToJsonOptions class has the following properties.

• ExportRangeToJsonOptions.getExportAsString(): This exports the string value of the cells to JSON.
• ExportRangeToJsonOptions.getHasHeaderRow(): This indicates whether the range contains a header row.
• ExportRangeToJsonOptions.getIndent(): Indicates the indent.

The JsonUtility class exports the JSON using the export options set with the ExportRangeToJsonOptions class.

The following code sample demonstrates the use of ExportRangeToJsonOptions and JsonUtility classes to load the source CSV file and prints the JSON output in the console.

Sample Code

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Source directory
const sourceDir = path.join(__dirname, "data");

const loadOptions = new AsposeCells.LoadOptions(AsposeCells.LoadFormat.Csv);
// Load CSV file
const filePath = path.join(sourceDir, "SampleCsv.csv");
const workbook = new AsposeCells.Workbook(filePath, loadOptions);
const lastCell = workbook.getWorksheets().get(0).getCells().getLastCell();

// Set JsonSaveOptions
const jsonSaveOptions = new AsposeCells.JsonSaveOptions();
const range = workbook.getWorksheets().get(0).getCells().createRange(0, 0, lastCell.getRow() + 1, lastCell.getColumn() + 1);
const data = AsposeCells.JsonUtility.exportRangeToJson(range, jsonSaveOptions);

// Print JSON
console.log(data);
