Excel Javascript API : The process automatically exists without any error in console

Kishan Vaishnani 6 Reputation points


I have developed an Excel Javascript plugin using the React framework.

The add-in workflow is simple.

  1. Request data from Ui using APIs
  2. Passing entities' column names and authorized API keys
  3. Start writing data into an active Excel sheet by pulling the button.

During the Excel data writing, sometimes the ongoing process stopped without showing any errors in the console pane.

The maximum amount of data coming from APIs is 5-8K.

Below is the sample code.

try {
  var i = 0;
  // these data are coming from APIs
  var allCompanies =[12,32,33,43,45,66,12,32,10,12,21,90];
  allCompanies.forEach(async _company => {
    // calling APIs for each _docs and writing data for that companies
    await fetchData(_company).then(async (responseRows) => {
      await Excel.run(async (context) => {
        let sheet = context.workbook.worksheets.getActiveWorksheet();
        await context.sync();
        for (let i = 0; i < responseRows.length; i++) {
          // data operations into Exel sheet
		  // creating table, table header, applying Css
          // writting value to each cells
        await context.sync();
} catch (error) {
  console.log("error on appending data into excel " + error);

Any solution will be helpful to me.
