How To Open Big Spreadsheets

  1. First create a free account, then simply upload your CSV file by clicking +New > File Upload > Browse to select a file from your machine. You can zip your file to save time uploading. Don't want to download your file? No problem. Click the Link option in the lower part of the upload box and provide publicly accessible URL to your Excel, CSV, TSV or other file.
  2. Next your file will automatically upload (and unzip if necessary). For exceptionally large files you'll see a loading bar while the file parses.
  3. Once complete, click on the file name in your Library to view the spreadsheet file online. The viewer will open a spreadsheet in a new browser tab for viewing. Here you can filter, search, or create pivot tables with your spreadsheet.
