Post some example data into a code box opened with the forum's {I} or "running man" from the delimited file NOT anything opened with a spreadsheet program as they will often reformat some columns of a CSV file. Use a simple text program like NOTEPAD or similar. If there is any sensitive data such as names or such replace those with values like "xxxx" or "9999" so we don't see the values.
Second, post the code you used to read the file.
Third, describe what you expect the final data set to look like for other use.
Likely which ever method you used did not provide a wide enough field for some of the values.
Because someone gave you data in an unfriendly layout you will need to split the values out.
Most likely you will have to be able to tell use what the maximum number of dates/ lab names/ values will occur on a single row to get things to line up correctly.
