Interesting, I googled a bit of that XML block, and google's AI came back with below.
In the context of the XML structure of an Excel file (which is in the Open XML format, essentially a zipped collection of XML files), the code snippet <c r="A3" t="s"> represents a cell within a worksheet.
Here's a breakdown:
<c> : This is the XML tag representing a cell.
r="A3" : This attribute specifies the cell's location or reference, which is "A3" in this case.
t="s" : This attribute indicates the data type of the cell's value. The value "s" signifies that the cell contains a shared string.
Shared String Table:
When the t attribute is set to "s", the actual text content of the cell is not stored directly within the <c> element. Instead, the <v> element inside the <c> element will contain an index that refers to an entry in the Shared String Table.
The Shared String Table is a separate part of the Excel XML file, typically found in a file named xl/sharedStrings.xml . It's a space-saving optimization where duplicate strings are stored only once and referenced by multiple cells. This means that multiple cells containing the same text can all point to the same entry in the Shared String Table, reducing file size.
In summary, <c r="A3" t="s"> tells us:
This is a cell.
Its location is A3.
It contains a string, and its value is stored in the Shared String Table, referenced by an index within the <v> element.
