    <p><strong>No need to write your own...</strong></p> <p>The <a href="http://github.com/evanplaice/jquery-csv/" rel="noreferrer">jQuery-CSV</a> library has a function called <code>$.csv.toObjects(csv)</code> that does the mapping automatically.</p> <p><em>Note: The library is designed to handle any CSV data that is <a href="http://tools.ietf.org/html/rfc4180" rel="noreferrer">RFC 4180</a> compliant, including all of the nasty edge cases that most 'simple' solutions overlook.</em></p> <p>Like @Blazemonger already stated, first you need to add line breaks to make the data valid CSV.</p> <p><strong>Using the following dataset:</strong></p> <pre><code>heading1,heading2,heading3,heading4,heading5 value1_1,value2_1,value3_1,value4_1,value5_1 value1_2,value2_2,value3_2,value4_2,value5_2 </code></pre> <p><strong>Use the code:</strong></p> <pre><code>var data = $.csv.toObjects(csv): </code></pre> <p><strong>The output saved in 'data' will be:</strong></p> <pre><code>[ { heading1:"value1_1",heading2:"value2_1",heading3:"value3_1",heading4:"value4_1",heading5:"value5_1" } { heading1:"value1_2",heading2:"value2_2",heading3:"value3_2",heading4:"value4_2",heading5:"value5_2" } ] </code></pre> <p><em>Note: Technically, the way you wrote the key-value mapping is invalid JavaScript. The objects containing the key-value pairs should be wrapped in brackets.</em></p> <p>If you want to try it out for yourself, I suggest you take a look at the <a href="http://evanplaice.github.io/jquery-csv/examples/basic-usage.html" rel="noreferrer">Basic Usage Demonstration</a> under the 'toObjects()' tab.</p> <p><em>Disclaimer: I'm the original author of jQuery-CSV.</em></p> <p><strong>Update:</strong></p> <p>Edited to use the dataset that the op provided and included a link to the demo where the data can be tested for validity.</p> <p><strong>Update2:</strong></p> <p>Due to the shuttering of Google Code. <a href="http://github.com/evanplaice/jquery-csv/" rel="noreferrer">jquery-csv has moved to GitHub</a></p>

    1. COIOW, "toObject" is or can be thought of as "toJSON", no? And, is the colon following the call to toObjects(csv) a typo? IOW, shouldn't that be a semicolon?

    2. CO@ClayShannon toJSON() (ie JSON.stringify()) implies that the CSV data is parsed and outputted in string format (ie text/json). toObjects actually maps the CSV into memory as an array of objects where the column names are used as the key names. $.csv.toObjects() is the CSV equivalent to JSON.parse(). The output above is just the simplify what the data would look like in memory.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
