cfspreadsheet 另存为 .csv，Excel 表示 "The file format and extension of FILE.csv don't match."

Question

我创建了一个冷聚变页面，用于将 MYSQL 中的客户列表输出到 CSV 文件中，以便轻松上传到 SalesForce.com

我可以生成包含所有正确信息的文件。但是，当我尝试使用 excel 打开它时，出现错误： "The file format and extension of 'SalesForceDailyLeads-20160613125138.csv' don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?" 我可以打开它（excel for MAC），但在我看来，CFSpreadsheet 没有创建合法的 .csv 文件，而是创建了一个 xlsx。

    <cfset FileCSV = "SalesForceDailyLeads-#dateformat(getBatch.BATCH,"yyyymmdd")##timeformat(getBatch.BATCH,"HHmmss")#.csv" >
    <cfset filename = "/SF/#fileCSV#">



    <cfset s = spreadsheetNew() >
    <cfset spreadsheetAddRow(s, "FIRST, LAST, MIDDLE, STREET, CITY, ZIP, STATE")>

    <cfinclude template="SFgetList.cfm">

    <cfset spreadsheetAddRows(s, getList)>

    <cfspreadsheet
        action="write"
        overwrite = "true"
        format ="csv"
        name ="s"
        filename ="#filename#"
        >

如果我创建一个 XLS 文件，我不会像使用 CSV 文件那样遇到问题。这是代码、CFSpreadsheet 或 excel（对于 mac）的问题吗？我可以修复它吗？

Answer 1

使用 cffile 而不是 cfspreadsheet 创建文件。每 the documentation:

The cfspreadsheet tag writes only XLS[X] format files. To write a CSV file, put your data in a CSV formatted string variable and use the cffile tag to write the variable contents in a file.

谢谢！当然，在我发布这篇文章之后，我立即找到了文档，发现我使用不正确，所以我改用了 CFFILE。我使用了我发现的 script/function 来做到这一点。然而，将查询转换为 CSV 需要一些工作——幸运的是，其他人已经做到了。如果有人想看到它：我在这里得到了 querytoCSV 脚本： https://gist.github.com/CreativeNotice/2775372

         * @param  {String}     d               {required}  Delimiter to use in CSV, defaults to a comma (,)
         * @return {String}                                         CSV content

cfspreadsheet 另存为 .csv，Excel 表示 "The file format and extension of FILE.csv don't match."

cfspreadsheet save as .csv, Excel says "The file format and extension of FILE.csv don't match."
