我正在尝试使用 SheetJS 读取 .xlsx 文件并将其转换为 JSON。我能够读取简单的（没有合并单元格）.xlsx 文件并将其转换为 JSON，但我无法正确处理合并单元格。
问题是我有一个 .xlsx 文件，其中包含不同语言的产品。
我尝试在不同的网站和 SheetJS 的 github 存储库上寻找解决方案https://github.com/sheetjs/js-xlsx/#json https://github.com/sheetjs/js-xlsx/#json取得了平庸的成功。主要解决如何编写合并单元格。
function handleFile(e) {
var files = e.target.files, f = files[0];
var reader = new FileReader();
reader.onload = function(e) {
var data = new Uint8Array(e.target.result);
var workbook = XLSX.read(data, {type: 'array'});
let result = '';
let sheet_name_list = workbook.SheetNames;
// iterate through sheets
sheet_name_list.forEach(function (y) {
workbook.Sheets[y]['!merges'].map(r => {
let startChar = XLSX.utils.encode_range(r).split(':')[0].replace(/[^a-zA-Z]+/g, '');
let endChar = XLSX.utils.encode_range(r).split(':')[1].replace(/[^a-zA-Z]+/g, '');
let number = XLSX.utils.encode_range(r).split(':')[0].match(/[+-]?\d+(?:\.\d+)?/g)[0];
for (let i = numbersFromLetters(startChar); i < numbersFromLetters(endChar); i++) {
workbook.Sheets[y][numbersToLetters(i + 1) + number] = {t:'s'};
workbook.Sheets[y][numbersToLetters(i + 1) + number].v = workbook.Sheets[y][XLSX.utils.encode_range(r).split(':')[0]].v;
workbook.Sheets[y][numbersToLetters(i + 1) + number].h = workbook.Sheets[y][XLSX.utils.encode_range(r).split(':')[0]].v;
workbook.Sheets[y][numbersToLetters(i + 1) + number].w = workbook.Sheets[y][XLSX.utils.encode_range(r).split(':')[0]].v;
workbook.Sheets[y][numbersToLetters(i + 1) + number].r = '<t>' + workbook.Sheets[y][XLSX.utils.encode_range(r).split(':')[0]].v + '</t>';
}
});
// Convert the cell value to JSON
//let roa = XLSX.utils.sheet_to_json(workbook.Sheets[y]);
//let roa = XLSX.utils.sheet_to_json(workbook.Sheets[y], {range: 1});
let roa = XLSX.utils.sheet_to_json(workbook.Sheets[y], {header: 1});
//let roa = XLSX.utils.sheet_to_json(workbook.Sheets[y], {skipHeader: true});
//let roa = XLSX.utils.sheet_to_json(workbook.Sheets[y], {header: 1, range: 1});
if (roa.length > 0) result = roa;
});
console.log(result);
};
reader.readAsArrayBuffer(f);
}
For better perception this is an example excel file with merged language cell:
我想要这个结果：
[
{ "languages":
[
{
"language": "US",
"name": "blue pants"
},
{
"language": "DE",
"name": "blaue Hose"
},
{
"language": "ES",
"name": "pantalones azules"
}
],
"price": 29.9,
"category": "pants"
},
...
]
根据我执行的注释代码的哪一部分，我会得到不同的结果，这些结果看起来与我想要实现的代码类似，或者至少可以进一步使用。但对于每一个结果，我都需要进一步摆弄，在我看来，可能会有更好的解决方案。
const workbook = XLSX.readFile(fileName, readOptions);
const sheetNames = workbook.SheetNames;
for (let worksheet of sheetNames) {
if (workbook.Sheets[worksheet]['!merges'])
workbook.Sheets[worksheet]['!merges'].map((merge) => {
const value = XLSX.utils.encode_range(merge).split(':')[0];
for (let col = merge.s.c; col <= merge.e.c; col++)
for (let row = merge.s.r; row <= merge.e.r; row++)
workbook.Sheets[worksheet][String.fromCharCode(65 + col) + (row + 1)] = workbook.Sheets[worksheet][value];
});
