When to convert ODS to PDF
ODS is ideal for editing in LibreOffice or OpenOffice. PDF is better when the numbers and layout are final and recipients should not need spreadsheet software. Check print areas, page orientation and scaling in the source before converting.
Review the finished pages
Wide tables may span several pages. Open the PDF and check column breaks, repeated headers and charts. Use Compress PDF afterward if image-heavy sheets create a large file, or Merge PDF to package the result with a report.
