问题
I am able to read and process *.xlsx files using an input element of type file and the library exceljs. Also see example code below.
Unfortunately, exceljs does not seem to support open document spreadsheet files *.ods. (The worksheet
is undefined).
=> How can I read and process *.ods files with javascript?

https://github.com/exceljs/exceljs/issues/716
static async readFile(file){
await this.__initializeExcel();
const workbook = new Excel.Workbook();
await workbook.xlsx.load(file);
const worksheet = workbook.worksheets[0];
var data = [];
const numberOfRows = worksheet.rowCount;
for (let rowIndex = 1; rowIndex <= numberOfRows; rowIndex++) {
const row = worksheet.getRow(rowIndex);
const rowValues = row.values;
data.push(rowValues);
rowValues.shift();
}
return data;
}

Thanks to the comment of DigitalDrifter I managed to read and process *.ods files with sheetjs/xlsx:
https://github.com/SheetJS/sheetjs
npm install xlsx --save
If you use script tags fro import, please make sure to import xlsx.full.min.js
instead of xlsx.min.js
. Otherwise you'll get an error Cannot find file [Content_Types].xml in zip
.
static async readOdsFile(file){
await this.__initializeXlsx(); //imports xlsx.full.min.js by script tag
return new Promise((resolve, reject)=>{
var reader = new FileReader();
reader.onload = event => {
try{
var result = reader.result;
var dataArray = new Uint8Array(result);
var workbook = Xlsx.read(dataArray, {type: 'array'});
const firstSheetName = workbook.SheetNames[0];
const worksheet = workbook.Sheets[firstSheetName];
const data = Xlsx.utils.sheet_to_json(worksheet,{header:1});
resolve(data);
} catch(error){
reject(error);
}
};
try{
reader.readAsArrayBuffer(file);
} catch (error){
reject(error);
}
}) ;
}
