# Source Script Node (Table)

This node allows you to customize data extraction and manipulation then return data in tabular form to the following node.

Example: Read tabular data from a file (e.g., CSV) and return it as a table or structured data.

```javascript
var tableContent = FileUtil.readFile("d:\\tmp\\file.csv");
// Perform any required operations on the table
return tableContent;
```

#### Example: Retrieve data from API and return in Tabular format

<pre class="language-typescript"><code class="lang-typescript">// Retrieve exchange rates from the API
var request = HttpUtil.get("https://boi.org.il/PublicApi/GetExchangeRates");
var jsonContent = JsonUtil.parse(request.asString().getBody());
var exchanges = jsonContent.exchangeRates;

// Create a table to store the data
var table = SuiteTable.create("MyTable");
table.addStringColumn("key");
table.addDoubleColumn("rate");
table.addStringColumn("lastupdate");

// Populate the table with data from the API
for (var i = 0; i &#x3C; exchanges.size(); i++) {
    var item = exchanges[i];
    var key = item.key.asText();
    var rate = item.currentExchangeRate.asDouble();
    var date = item.lastUpdate.asText();
    
    var row = {
        "key": key,
        "rate": rate,
        "lastUpdate": date
    };
    

<strong>    table.addRow(row);
</strong>}

// Filter table with some type of selection example:
var selection = table.stringColumn("key").isEqualTo("USD");
var filteredTable = table.where(selection);

// Return the filtered table
return filteredTable;
</code></pre>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.b2winsuite.com/5.5/scripting/scripting-in-b2data/custom-script-nodes/source-script-node-table.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
