I know there are already many questions similar to this one (I have read most of them), but I still haven't found a solution so I figured I'd ask my own question with specifics.
Ok, so I have spent the past two days researching and trying to parse an Excel (.xlsx) spreadsheet in php. I've tried using the PHPExcel Library, however, it times out when trying to load the spreadsheet into memory. The spreadsheet is not very large, only 240kb, but it does have 40+ worksheets each heavily formatted (i.e. cell color, font size/color, etc...). Since I don't need any of the formatting I tried $objReader->setReadDataOnly(true); in order to ignore it, but it still times out when trying to read the file.
So my next step was to try and load only the last couple of worksheets I actually needed using, $objReader->setLoadSheetsOnly(array(42,43,44,45)); This loads successfully, but now the problem is that the last sheets are almost completely formulas which total and read data from the previous worksheets. And since I excluded those earlier worksheets in order to load the document I can't use $cell->getCalculatedValue(); when retrieving each cell's value, thus making everything else obsolete.
So my question is, is there something else I can do in order to load and read this Excel spreadsheet?
Is there another library I should try and use? Or a completely different method I should try, since my end goal is to be able to upload parts of the data to a database?
Here is a link to the particular spreadsheet I am using.
Thanks for taking the time to read this and for any help you can provide.
