Spreadsheet library for Lucee (and Adobe ColdFusion)

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.

Rationale

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.

Library vs Extension

Benefits

  • 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.
  • Offers many additional functions and options (see below).
  • Fixes various outstanding bugs/omissions.
  • No dependency on Lucee within the included jar files.
  • Also works with Adobe ColdFusion (see below).

Downsides

  • Existing code needs adapting to invoke the library. Existing CFML spreadsheet functions and the <cfspreadsheet> tag won't work with it.

Adobe ColdFusion

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.

Minimum Requirements for version 2.x

  • 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.

Usage

The following are the essential files/folders you will need depending on which engine you are using:

Lucee

lib-osgi.jar
osgiLoader.cfc
Spreadsheet.cfc

Adobe ColdFusion

javaLoader/
lib/
Spreadsheet.cfc

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
<cfscript>
spreadsheet = New spreadsheetLibrary.Spreadsheet();
data = QueryNew( "First,Last", "VarChar, VarChar", [ [ "Susi", "Sorglos" ], [ "Frumpo", "McNugget" ] ] );
workbook = spreadsheet.new();
spreadsheet.addRows( workbook, data );
</cfscript>

init()

When instantiating the library, the init() method must be called. This will happen automatically if you use the New keyword:

spreadsheet = New spreadsheetLibrary.Spreadsheet();

If using CreateObject() then you must call init() explicitly:

spreadsheet = CreateObject( "component", "spreadsheetLibrary.Spreadsheet" ).init();

Using a mapping

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();).

How to create mappings (StackOverflow).

Additional Convenience methods

Enhanced Read() method

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:

  • fillMergedCellsWithVisibleValue
  • includeHiddenColumns
  • includeRichTextFormatting
  • password to open encrypted spreadsheets
  • csvDelimiter
  • queryColumnTypes

Date formats

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 );

JavaLoader

From version 2.14.0, Lucee loads the POI and other required java libraries using OSGi. This is not yet supported with Adobe ColdFusion which by default uses an included version of Mark Mandel's JavaLoader.

For more details and options see: Loading the POI java libraries

CommandBox Installation

You can also download this library through CommandBox/Forgebox.

box install 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");

Test Suite

The automated tests require TestBox 2.1 or later. You will need to create an application mapping for /testbox

Credits

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. Header/Footer image functionality is based on code by Axel Richter.

JavaLoader is by Mark Mandel.
