ColdFusion (9) mysteriously removes characters 'D' and 'F' after numbers when exporting to Microsoft Excel (2007)

问题

Here's some code snippets for an example:

theSheet = SpreadsheetNew("Rates","True");
SpreadsheetAddRow(theSheet,"4A,4B,4C,4D,4E,4F,4G,4H,4I,4J");
SpreadsheetAddRow(theSheet,"4K,4L,4M,4N,4O,4P,4Q,4R,4S,4T");
SpreadsheetAddRow(theSheet,"4U,4V,4W,4X,4Y,4Z,4D4,4F4");

and

<cfheader name="content-disposition" value="attachment; filename=#GetTickCount()#.xlsx">
<CFHEADER NAME="Expires" VALUE="#now()#">
<cfcontent type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" variable="#SpreadsheetReadBinary(theSheet)#"/>

The issue is that "4D" and "4F" (and not the others) lose the 'D' and 'F' and are formatted as a number.

I tried this:

formatText = StructNew();
formatText.dataformat="@";
SpreadsheetFormatColumns(theSheet,formatText,"1-10");

I verified that this set the format in Excel to "Text", but now I just see the number 4 in a Text-formatted cell! I also tried using the ' character, but when it opens in Excel, it just shows the ' instead of literalizing the cell.

This is rather strange; anybody have an idea about what's going?

回答1:

It seems that a workaround is to set the cell formula to be the literal "4D".

theSheet = SpreadsheetNew("Rates","True");
SpreadsheetAddRow(theSheet,"4A,4B,4C,,4E,,4G,4H,4I,4J");
SpreadsheetSetCellFormula(theSheet, """4D""", 1, 4);
SpreadsheetSetCellFormula(theSheet, """4F""", 1, 6);
SpreadsheetAddRow(theSheet,"4K,4L,4M,4N,4O,4P,4Q,4R,4S,4T");
SpreadsheetAddRow(theSheet,"4U,4V,4W,4X,4Y,4Z,4D4,4F4");

I still don't know why this is happening, but my idea is that SpreadsheetAddRow() and SpreadsheetSetCell() are interpreting 4D and 4F as numeric and are interpreting the D and F and suffixes standing for Double and Float, and stripping them out after conversion.

You can submit the bug to Adobe by going to https://bugbase.adobe.com/index.cfm.

回答2:

You should try to use D char code explicitly chr(68) instead of "D".

回答3:

You might try the old spreadsheet trick -- going back to Lotus days -- of coercing values to text by starting the entry with a single quote: '4D.

回答4:

I updated code from a related stack question to search for characters (to use by prepending or appending to the given text) to hide this ColdFusion feature:

WorkBook = spreadsheetNew('Test', true);
RowNumber = 1;  
for (i = 1; i <= 255; i++){
    SpreadSheetSetCellValue(WorkBook, i, RowNumber, 1);

    // what character are we displaying
    SpreadSheetSetCellValue(WorkBook, chr(i), RowNumber, 2);

    // see if appending chr(i) allows 4F to display
    SpreadSheetSetCellValue(WorkBook, "4F#chr(i)#", RowNumber, 3);

    // see if appending chr(i) allows 4F to display
    SpreadSheetSetCellValue(WorkBook, "#chr(i)#4F", RowNumber, 4);
    RowNumber ++;
}

Turns out prepending or appending nonprintable characters chr(127) and chr(160) maintain the presentation of 4F or 4D
