我有一个工具，大致可以满足你的需求，不幸的是我的工具是用powershell编写的，我把它作为一个答案，希望你或其他人可以用javascript重新实现它。
Expand-csv遍历csv文件，并将数据作为实际值插入模板中的变量数据。这会产生一系列基本形式相同但内容不同的扩展。
对于您的示例，csv文件看起来与您提供的文件类似：

模板文件如下所示：

<br>Welcome to information! Your Session Leader for $id<tab> is $Session_Leader_first_Name<br>

以下命令将使用这些输入运行Expand-csv，并将输出存储在文件中。

Expand-Csv myfile.csv format.tmplt  > result.html

结果会是这样的：

<br>Welcome to information! Your Session Leader for 1<tab> is Ollie<br>
<br>Welcome to information! Your Session Leader for 2<tab> is Elie<br>
<br>Welcome to information! Your Session Leader for 3<tab> is Gregorio<br>
<br>Welcome to information! Your Session Leader for 4<tab> is Caryl<br>
<br>Welcome to information! Your Session Leader for 5<tab> is Manuel<br>
<br>Welcome to information! Your Session Leader for 6<tab> is Baudoin<br>
<br>Welcome to information! Your Session Leader for 7<tab> is Franz<br>
<br>Welcome to information! Your Session Leader for 8<tab> is Nani<br>
<br>Welcome to information! Your Session Leader for 9<tab> is Phil<br>
<br>Welcome to information! Your Session Leader for 10<tab> is Maryjane<br>
<br>Welcome to information! Your Session Leader for 11<tab> is Siouxie<br>
<br>Welcome to information! Your Session Leader for 12<tab> is Carny<br>
<br>Welcome to information! Your Session Leader for 13<tab> is Stephan<br>
<br>Welcome to information! Your Session Leader for 14<tab> is Linda<br>
<br>Welcome to information! Your Session Leader for 15<tab> is Kip<br>

模板中有两个变量，$id和$Session_Leader_first_Name。美元符号使它们看起来像powershell变量。名称对应于csv文件中的两个字段。我添加了一些HTML标记，只是为了显示它们在结果中通过。
最后是Expand-Csv：

.NOTES
    Script: Expand-Csv    Rev:  3.2
    Author: DGC           Date: 2-21-19
.SYNOPSIS
    Generates multiple expansions of a template,
    driven by data in a CSV file.
.DESCRIPTION
    This function is a table driven template tool. 

    It generates output from a template and
    a driver table.  The template file contains plain
    text and embedded variables.  The driver table 
    (in a csv file) has one column for each variable, 
    and one row for each expansion to be generated.

function Expand-csv {
    [CmdletBinding()]
    Param (
       [Parameter(Mandatory=$true)] [string] $driver,
       [Parameter(Mandatory=$true)] [string] $template
    )
    Process {
       Import-Csv $driver | % {
           $_.psobject.properties | % {Set-variable -name $_.name -value $_.value}
           Get-Content $template | % {$ExecutionContext.InvokeCommand.ExpandString($_)} 
       }
    }
