How do I export LogTag data for Microsoft Excel?

LogTag Analyzer allows you to save in a variety of formats

Exporting your LogTag data to Excel is a straightforward process that gives you flexibility for reporting, analysis, and record-keeping. Whether you’re managing vaccine fridge logs or monitoring food storage temperatures, having your data in a spreadsheet format makes it easier to share and interpret.

Here’s how to do it – plus a few tips to make the process smoother.

Option 1: Automatically save CSV files during download

If you regularly download data from your LogTag, you can set LogTag Analyzer to automatically save a CSV file alongside the standard LTD file.

To enable automatic CSV export:

  1. Open LogTag Analyzer.

  2. Go to Edit > Options.

  3. Select the Export and Reports tab.

  4. Tick the box next to CSV (Comma delimited).

  5. Click OK to save your settings.

From now on, every time you download a LogTag, a CSV file will be saved in the same folder as your LTD file – usually in My Documents > My LogTag Data.

Option 2: Export a previously saved file

If you’ve already downloaded a LogTag file and want to export it to Excel:

  1. Open the file in LogTag Analyzer.

  2. Go to File > Save As….

  3. In the Save as type dropdown, select CSV (Comma delimited).

  4. Choose your save location and click Save.

You can now open the CSV file directly in Excel. If needed, you can adjust the list separator in Windows settings to match your preferred format.

Option 3: Copy and paste directly into Excel

If you only need a quick snapshot of the data:

  1. Open the LogTag file in Analyzer.

  2. Navigate to the Data or Summary tab.

  3. Select the relevant rows.

  4. Go to Edit > Copy.

  5. Open Excel and paste the data.

This method is handy for quick reports or when you only need part of the dataset.

Tips for smoother exporting

  • Organise your folders Keep your LogTag data in a dedicated folder (e.g. on a network drive) so it’s easy to access and share with your team.
  • Download regularly Frequent downloads reduce the risk of memory overflow and make it easier to track trends over time.
  • Use Excel filters Once your data is in Excel, use filters and conditional formatting to highlight temperature excursions or sort by date.

If you run into any issues or need help setting up your export preferences, feel free to contact us or your local distributor. We’re here to make temperature monitoring as simple and reliable as possible.

Latency explained

What is latency?

Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.

For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.

Differrnt connections

Connecting your logger

Depending on the type of logger you have, connecting your logger to your PC means either:

  • inserting into the Reader,
  • plugging it into a USB port, or
  • connecting it via a USB cable.

What's so good about USB?

First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data. 

The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
