how to recover the data:
copy line 1 at the end and paste into a .txt file (preferably notepad ++)
save the .txt file
open an Excel file
In Excel, open the .txt file as a .csv file with delimiter: space
You will get your data with the columns: year, day, hour, x, y, z

After it is necessary to reconstitute Julian date, then to constitute a file xyz

I made an Excel table that prepares all that.

Attention: Excel is limited in the number of rows (65536)
