Excel RTD server sourcing data from Rabbit-MQ

1. Clone the repository and go to its folder.

2. Compile the code using Visual Studio, MSBuild or via this handy script file:

   build.cmd

3. Register the COM server by running the following script in admin command prompt:

   register.cmd

4. Install RabbitMQ https://www.rabbitmq.com/download.html with all default options, for now.

Once the RTD server has been installed, you can use it from Excel via the RTD macro. This is the syntax:

=RTD("rabbit",, $HOST_URI, $EXCHANGE, [$QUEUE], [$ROUTING_KEY])   // returns whole message as a string
=RTD("rabbit",, $HOST_URI, $EXCHANGE, [$QUEUE], [$ROUTING_KEY], $FIELD)  // requires JSON formatted messages
=RTD("rabbit",, "localhost", "my.x", "my.q", "my.rk")   // returns whole message as a string

Format [amqp://][userName:password@]hostName[:portNumber][/virtualHost]

Examples: localhost guest:guest@localhost:5672/

Format: [name[:type[:durability[:auto-delete[:arguments]]]]]

type:

• direct (default)
• fanout
• topic
• match

name: Exchange name

• "" empty string (default)
• my.exchange.name

durability: exchanges survive broker restart

• true
• false (default)

auto-delete: exchange is deleted when last queue is unbound from it

• true
• false (default)

arguments: optional, used by plugins and broker-specific features

• json string

Examples: my.exchange:topic:false:true :fanout EXCHANGE
my.exchange:topic:false:true:{"my.arg":42}

Format name[:durable[:exclusive[:auto-delete[:arguments]]]

name: This is supported, the name of the queue

The following are TODO

durable: (the queue will survive a broker restart)

• true (default)
• false

exclusive: (used by only one connection and the queue will be deleted when that connection closes)

• true
• false (default)

auto-delete: (queue that has had at least one consumer is deleted when last consumer unsubscribes)

• true
• false (default)

arguments: (optional; used by plugins and broker-specific features such as message TTL, queue length limit, etc)

Format: #.string1.string2.*

TBA: For use with JSON messages

Have Fun!
