----------------------------------
Nick,
Could you please explain the intended goal of parsing an excel file?
Conceptually an excel file is a collection of records where typically the cells
in each row are the values for the fields defined in the headers in the first
row. I am not sure an excel file always makes sense as just a collection of
non-empty cells. So - with the current implementation it is impossible to
correctly extract a list of records from a 2010 excel file. Works with excel 97
BTW. Any feedback would be greatly appreciated.

> Key: TIKA-1020
> URL: https://issues.apache.org/jira/browse/TIKA-1020
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.2
> Environment: java 1.6 & 1.7
> Reporter: Neil Blue
> Labels: newbie, patch
>
> When parting an excel 2010 table, if a worksheet has a missing value, then it
> is not reported in the sax handler. As a result a missing value can result in
> unordered data.
> For example given the table:
> {code:title=Bar.java|borderStyle=solid}
> A B B
> 1 2 3
> 4 6
> 7 8 9
> {code}
> the returned sax handler reports elements
> {code:title=Bar.java|borderStyle=solid}
> <tr><td>A</td><td>B</td><td>C</td><tr>
> <tr><td>1</td><td>2</td><td>3</td><tr>
> <tr><td>4</td><td>6</td><tr>
> <tr><td>7</td><td>8</td><td>9</td><tr>
> {code}
> As a result the handler can detect that the third row as incomplete cell
> values but it is ambiguous which columns have missing data.
> As a possible fix for this excel 2010 xml data contains the cell reference
> value, which could be returned to the sax handler as an attribute.
> {code:title=Bar.java|borderStyle=solid}
