Efficiently converting arrays to strings in JavaScript using mapping techniques

My goal is to retrieve data through AJAX without formatting it as JSON, so I took the initiative to encode it myself.

The data I am working with consists of client records: where the pound sign (#) separates the client records, the pipe sign (|) separates the fields within each record, and the carat sign (^) distinguishes the field name from its corresponding value.

This is a simplified representation of the data:

name^James|email^<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ff8c90929a929e9693bf98929e9693d19c9092">[email protected]</a>#name^Bary|email^<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="583a392a21183a392a21763b3735">[email protected]</a>#...

Upon loading this data into Javascript, my objective is to format it into a 2-dimensional array similar to this:

clients = [
['name'=>'James','email'=>'<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="61120e0c040c00080d21060c00080d4f020e0c">[email protected]</a>'],
['name'=>'Bary','email'=><a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bedcdfccc7fedcdfccc790ddd1d3">[email protected]</a>]
]

Alternatively, an object format could also be considered. What would be the most effective method to accomplish this?

Caution: It is not advisable to include special characters (|,^,#) in your keys or values. If you encounter them, consider encoding with JSON for a smoother process. I highly suggest using JSON to avoid any manual work.

If you opt not to allow (|,^,#) in your keys and values, you can utilize the javascript split function. A sample code snippet is shown below:

var output=[];
var clients = input.split("#");

for (var client in clients)
{
  var outputClient={}
  var clientProps = client.split('|');
  for (var propPair in clientProps)
  {
     var propPairVal = propPair.split('^');
     outputClient[propPairVal[0]] = propPairVal[1];  
  }
  output.push(outputClient);
}

Nevertheless, using JSON is strongly recommended for its flexibility and decreased likelihood of bugs.
