基于typescript或json等文件的值从模板生成文件

我有一个SPFX Web部件,它接收用户数据,然后将数据发送到列表 this is how the list looks for context 并且所有的值都是这样存储的:

export interface SPListItem
{
   localIndex: number;
   ID: number;
   Title: String;
   CompanyName: string;
   ClientName: string;
   CurrentDate: string;
   PreferredDate: string;
   RequestedBy: string;
   TypeOf: string;
   Reason: string;
   Urgent: string;
   Department: string;
   Chargeable: string;
   EstimatedTime: string;
   approvedStatus: string;
}

在主要的Web部件类中:

private getListItemData(): void
{
    this._getListData()
        .then( ( response ) =>
    {
        let index: number = 0;
        response.value.forEach( ( item: SPListItem ) =>
        {
                this.listItems[ index ] = 
                {
                    localIndex: 0,
            Title: item.CompanyName + "-" + item.RequestedBy,
            CurrentDate: item.CurrentDate,          
                    Chargeable: item.Chargeable,
            ID: item.ID,

            CompanyName: item.CompanyName,
            ClientName: item.ClientName,
            RequestedBy: item.RequestedBy,
            PreferredDate: item.PreferredDate,
            Department: item.Department,
            TypeOf: item.TypeOf,
            Urgent: item.Urgent,
            EstimatedTime: item.EstimatedTime,
            Reason: item.Reason,
            approvedStatus: item.approvedStatus,
                };
        
                index++;
        } );
        this.printListItemInfo();
        return;
    } )
    .catch( ( err ) =>
    {
        throw Error( err );
    } );
}

我正在寻找一种将这些数据放入预制文件的方法。(例如,有一个docx模板,复制模板并用值替换模板中的所有占位符)

我已经研究了一周的方法,我发现最接近的方法是使用 https://docxtemplater.com/ 正如它所说的和 https://pnp.github.io/pnpjs/sp/files/#update-file-content 但在经历了很多挫折之后,我相信这在我的情况下是行不通的。

目前,我有导出到json文件的值:

newGen.json:

{
    "Company Name"   : "a",
    "Client Name"    : "b",
    "Current Date"   : "c",
    "Preferred Date" : "d",
    "Requested By"   : "e",
    "Type"           : "f",
    "Reason"         : "g",
    "Urgent"         : "h",
    "Department"     : "i",
    "Chargeable"     : "j",
    "Estimated Time" : "k"
} 

(注意:我也导出了一个html文件,但在不手动将其转换为pdf或docx的情况下也遇到了类似的问题,这将无法实现目的)
