title: Excel Error: Removed Records: Sorting from /xl/worksheets/sheet10.xml part
body: <p>I'm almost sure I will have to create a new excel file, but maybe at least here I get some ideas what was the source of the problem.</p>
  
  <p>My excel file is constantly giving the following error: </p>
  
  <p>Excel found unreadable content in 'filename.xlsm'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes.</p>
  
  <p>So I do. And the file opens as repaired showing:</p>
  
  <p>Removed Records: Sorting from /xl/worksheets/sheet10.xml part.</p>
  
  <p><strong>The detail is that I don't even have a sheet10</strong></p>
  
  <p>Its a big excel file full of custom-objects. But I have no DB connections or autofilter so could not relate to <a href="https://stackoverflow.com/questions/19042181/autofilter-criteria-using-array-error-too-large-string">AutoFilter Criteria Using Array (Error) - Too Large String?</a> or <a href="https://stackoverflow.com/questions/18539267/xlsx-error-removed-records-named-range-from-xl-workbook-xml-part-when-tried">xlsx error: &quot;Removed Records: Named range from /xl/workbook.xml part&quot; when tried to resolve errors</a>.</p>
  
  <p>Anyone has a clue what's going on?</p>
  
  <p>tks in advance</p>
