• Direct export of data displayed on the chart (within display limits):

  • Available for all chart types other than maps.

    • In tables with pagination enabled, exports only the current page data.

  • The following formats are available:

    • XLSX
    • CSV
    • Markdown (copied to clipboard)

  • File upload begins immediately.

  • Available in all service plans.

• Background data export with extended limits of up to 1 GB:

  • Available only for paginated Tables created in the wizard. Exports data from all the table's pages.
  • Format: CSV file.
  • First, the file is generated in the background, then a download link is created. File preparation takes up to 30 minutes.
