<p>The spreadsheet block reads xlsx files and converts it into a live table.<br />
You can specify what cells should be editable. Editing fields will affect existing cell calculations.</p>
<p>For some reason WordPress prohibits the upload of <code>xslx</code> files. You can workaround this issue by renaming the file to <code>xls</code> (for now).</p>
<h4>Usage</h4>
<p>To use simply add a block to a page or post and choose ‘Spreadsheet block’. Upload an xls or xlsx spreadsheet file from the sidebar.</p>
<p>From the cell options (in the block) you can set which cells are editable and which cells will be rendered as table head.</p>
<p>Click the eye behind a sheet name to make specific sheets invisible.</p>
