Export a trend

Download the values shown in the Trend Workspace as a CSV or Excel file, and know what each file contains.

At the end of this guide you have a file with the values of the tags on your chart, one row per moment and one column per tag.

Before you start

Export

  1. Wait until the chart has loaded. The export buttons are disabled while it loads.
  2. If you need amounts as well as values (energy from power, volume from flow), tick Show total over time.
  3. Next to Export, select CSV or Excel. The file is downloaded by your browser.
The figures table with Show total over time, the CSV and Excel export buttons and the Data column showing 1m avg plus min and max
  1. Show total over time adds the Total column.
  2. CSV downloads a text file.
  3. Excel downloads an .xlsx workbook.
  4. Data shows how the values were drawn. The file holds the same points as the chart: over long ranges these are averages per time step, not every stored value. For raw values, choose a shorter range first.

The file name holds the range, for example trend-20261015-1338-20261015-2138.csv.

What is in the files

  • First column time_utc (ISO time in UTC), second time_local (in your browser's time zone), then one column per tag named Tag · Device [unit].
  • One row per moment at which any tag has a value. A tag without a value at that moment has an empty cell.
  • Comma as separator and a dot as decimal sign, whatever your language, so other tools read it the same way. The file is UTF-8 and opens in Excel with device names intact.
time_utc,time_local,Speed · MFB_RTM_L1_FILLER [pcs/min],Speed · MFB_RTM_L2_FILLER [pcs/min]
2026-10-15T11:38:00.000Z,2026-10-15 13:38:00.000,392.4,231.7
  • Sheet Data: the local time (the time zone is in the header) and one column per tag.
  • Sheet Summary: From, To and Time zone of the range, then one row per tag with Last, Min, Avg, Max, Total and Data, as in the table on screen.

What's next

  • Reports: scheduled, formatted output of the same data.
  • Telemetry API: read stored values from your own program.
