Question

我有一个我想编辑的模板电子表格，所以我可以在其中插入数据。

然而，显然应该工作的代码只会引发NullPointerException。错误总是发生在代码的“写入”部分。电子表格读得很好。

<!--- Read spreadsheet --->
    <cfspreadsheet action="read"
    src="#theFileCopy#"
    name="sObj" />
    <!--- Set cell value --->
    <cfset spreadsheetSetCellValue(sObj, "Test", 3, 3)>
    <!--- Write spreadsheet --->
    <cfspreadsheet action="write" overwrite="true"
    filename="#theFileCopy#"
    name="sObj" />

堆栈追踪：

Answer 1

问题是该文件是xlsx格式。出于某种原因，Coldfusion将读取xslx罚款，但不会将其写回。文档确实说电子表格动作=只写xls。很想知道这样做的任何方法。
