I have an image with multiple linear length measurements (Tape Measure data). When I try to export them I get the option to export only the data that is currently active in the table, i.e. one data point/measurement. This is bit cumbersome for images where I have 10 or so measurements. Is there an easy way to export all these measurements at once to a data file?

You can only export one datatable at a time but you might be able to make all your measurements with a single tape measure. If you're working with a single image then by default the "video" has 10 frames but you can always increase that in the clip settings. Create the tape, then uncheck the "fixed" checkbox in it's track menu. Then you can move the tape to a different position in each frame, and each length will be in a different row of the data.
If you have to make all measurements in a single frame of a video, there's another way but more tedious: click the Table button in the table view, click the Text Columns button and choose Create to create a new editable text column. Then manually enter the lengths into that column. Again this puts all data in a single table, though it's not clear this is less work than exporting them separately...
Hope this helps! Doug

Apologies for the trailing message, but I encountered an issue while using this method. The first couple of images worked just fine but the rest of them actually load multiple different images as frames, as if it was a video. So if I click on a new frame point to try and adjust the measuring tape, the image changes.
I tried different things to change this behavior (copy/paste frame, trimming clip, etc.) but nothing works. Please can you tell me if there is a way to do this?

It sounds like your images are numbered sequentially. When you open an image with a name that ends in a number, then when Tracker opens it it will look for additional images with the same name and sequential numbering. If it finds them it opens the whole image sequence as a video with each image being a single frame as you describe.
The fix is to rename images to NOT end in numbers. Then it will be opened as a 10-frame video with the same image in every frame (you can easily change the frame count after opening it).

Once again, thank you so much. It is precisely this that is happening. I will rename the images to avoid numbering sequence at the end of the filename.
