Originally adapted from the https://github.com/teamcfadvance/cfspreadsheet-railo extension, this is a standalone library for reading, creating and formatting spreadsheets in Lucee Server which does not require installation as an extension. It can also be used with Adobe ColdFusion.
Unlike Adobe ColdFusion, Lucee doesn't support spreadsheet functionality out of the box. An extension exists for Lucee, but I decided to create a standalone library which doesn't depend on customisation of the engine.
- No installation required, either at the server or individual web context level.
read()method offers all the features of the<cfspreadsheet action="read">tag in script in addition to the basic options ofSpreadsheetRead().- Offers a number of additional functions and options (see below)
- Fixes various outstanding bugs/omissions.
- No dependency on Lucee within the included jar files.
- Invoking the library doesn't create a workbook instance (a.k.a. Spreadsheet Object), meaning:
- a blank workbook isn't created unnecessarily when reading an existing spreadsheet
- the library can be stored as a singleton in application scope
- Also works with Adobe ColdFusion (see below)
- Written entirely in CFML script.
- Existing code needs adapting to invoke the library. Existing CFML spreadsheet functions and the
<cfspreadsheet>tag won't work with it.
Although primarily intended for Lucee, the library can be run under ColdFusion 2016 or higher. This may be useful where you want to your codebase to be cross-compatible between the two engines.
- Java 8 or higher
- Lucee 5.x or higher
- Adobe ColdFusion 2016 or higher
If you are running Java 6 and 7, Lucee 4.5 or ACF11, please use version 1.x.
Note that this is not a Lucee extension, so does not need to be installed. To use it, simply copy the files/folders to a location where Spreadsheet.cfc can be called by your application code.
The following example assumes the file containing the script is in the same directory as the folder containing the spreadsheet library files, i.e.:
- root/
- spreadsheetLibrary/
- Spreadsheet.cfc
- etc.
- script.cfm
- spreadsheetLibrary/
<cfscript>
spreadsheet = New spreadsheetLibrary.Spreadsheet();
data = QueryNew( "First,Last", "VarChar, VarChar", [ [ "Susi", "Sorglos" ], [ "Frumpo", "McNugget" ] ] );
workbook = spreadsheet.new();
spreadsheet.addRows( workbook, data );
</cfscript>
You will probably want to place the spreadsheet library files in a central location with an application mapping, and instantiate the component using its dot path (e.g. New myLibrary.spreadsheet.Spreadsheet();).

In Adobe ColdFusion, the SpreadsheetRead() script function is limited to just returning a spreadsheet object, whereas the <cfspreadsheet action="read"> tag has a range of options for reading and returning data from a spreadsheet file.
The read() method in this library allows you to read a spreadsheet file into a query and return that instead of a spreadsheet object. It includes all of the options available in <cfspreadsheet action="read">.
<cfscript>
myQuery = spreadsheet.read( src=mypath, format="query" );
</cfscript>
The read() method also features the following additional options not available in ColdFusion or the Spreadsheet Extension:
fillMergedCellsWithVisibleValueincludeHiddenColumnsincludeRichTextFormattingpasswordto open encrypted spreadsheets
The following international date masks are used by default to read and write cell values formatted as dates:
- DATE =
yyyy-mm-dd - TIME =
hh:mm:ss - TIMESTAMP =
yyyy-mm-dd hh:mm:ss
An additional mask is used to output datetime values from the read() method into HTML or CSV formats:
- DATETIME =
yyyy-mm-dd HH:nn:ss
NB: Do not confuse DATETIME and TIMESTAMP. In general you should override the TIMESTAMP mask.
Each of these can be overridden by passing in a struct including the value(s) to be overridden when instantiating the Spreadsheet component. For example:
<cfscript>
spreadsheet = New spreadsheetLibrary.spreadsheet( dateFormats={ DATE: "mm/dd/yyyy" } );
</cfscript>
While the above will set the library defaults, you can format cells with specific masks using the dataFormat attribute which can be passed to formatCell and the other formatting methods, as part of the format argument:
// display datetime value with millisecond precision
spreadsheet.formatColumn( workbook , { dataformat: "yyyy-mm-dd hh:mm:ss.000" }, 1 );
A bundled version of Mark Mandel's JavaLoader will be used by default to load the POI and other required java libraries.
For more details and options see: Loading the POI java libraries
You can also download this library through CommandBox.
box install cfsimplicity/lucee-spreadsheet
It will download the files into a modules directory and can be used just the same as downloading the files manually.
If using ColdBox you can use either of the WireBox bindings like so:
spreadsheet = wirebox.getInstance("Spreadsheet@lucee-spreadsheet");
spreadsheet = wirebox.getInstance("LuceeSpreadsheet");
The automated tests require TestBox 2.1 or later. You will need to create an application mapping for /testbox
The code was originally adapted from the work of TeamCfAdvance. Ben Nadel's POI Utility was also used as a basis for parts of the read functionality.
JavaLoader is by Mark Mandel.
