Format the CSV file for a fast load import

  • Last UpdatedFeb 27, 2025

Important: The data points must be sorted in time sequential order for a successful "fast load" import.

The format for the fast load CSV file is essentially the same as the normal format, with a few exceptions.

For a general illustration of the CSV format, see General file format for a CSV import. For a detailed description of the normal format, see Format the CSV file for a normal import.

The fast load format exceptions are:

  • All data in the file is treated as original data. The Operation Type field in the file header is ignored.

  • The actual data values in the file must be in time sequential order, starting at the top of the file. This is the most important requirement. Values that have out-of-sequence timestamps are ignored. If a data value in the file has a timestamp that is earlier than the timestamp in the previous line in the file, the data value is discarded, regardless of whether it belongs to the same tag or a different tag.

  • The file should contain only one data value per line.
