    CSV format is very useful. Also useful is separating the data in the columns on each line with the tab character. Numbers and most spreadsheets handle this with no problems.

    It is very convenient to have this simple CSV format that is not tied to a particular spreadsheet app for storing data. Some programming languages, such as Python, have some functionality, in the form of additional packages, that enable you to read CSV files, analyze them, and generate plots from them. For example, if the first column is Date and the second column is High Temperature, you can create a plot that shows high temperature as a function of date.

    Thank you! I did not know about the plaint text mode in TextEdit.
    I use a backslash (\) to delimit, and I find LibreOffice helpful when opening a CSV file because it prompts me up front to specify how the fields are separated (fixed length or what delimiters).

    Please do a tutorial on Merging csv files into a master csv where quantities are combined if all headers are the same.
    Ie 2 quantity in one sheet, 3 on the next. Same headers, so combines to 5

    • @macmost
      @macmost  7 місяців тому

      I would just import them all into Numbers (or Excel) and combine them there using formulas and other techniques. How easy that is depends on your spreadsheet skills.

      Just google "convert PDF to CSV"

    • @macmost
      @macmost  Рік тому +1

      The best way is usually copy and paste. You can sometimes do it right into Numbers. If that doesn't work paste it into a text document and clean it up there first.

      A sample? Just to test this? You can do to a data site (US Census, etc) and download some CSVs if you like. Or just type one out in a TXT file with TextEdit. Just commands and returns, like this would work.

      @@Land-of-reason That's fine. You can do that. But put yourself in my shoes. Wikipedia and every single page on the first page of Google search results for "what does csv stand for" says it is "values." If I say "values" I get one complaint. But if I said "variables" I would definitely get more. I can't win, but I can at least go with the consensus. Oh, and here is another page at the same site (IBM) that says it is values: www.ibm.com/docs/en/bpmoc?topic=SS964W/com.ibm.wbpm.wid.data.doc/topics/ccsv.htm

    • @Land-of-reason
      @Land-of-reason Рік тому

      A CSV file is a table where the fields that make up that table are delimited with a ‘comma’.
      Within the context of a programme a ‘value’ will have a specific meaning.
      Within the context of a 70’s HP2100 or 21MX computer the value ‘102077’ octal meant ‘stop’. If you have a table of ‘Comma Separated Values’ each line within that file would represent the same thing - the stop code which would be nonsense.
      Despite what Wikipedia may claim the fields within the table must be variables and not values.

      CSV documents aren't full spreadsheets and just have the values in them, not formulas. Formulas would be specific to an app like Excel or Numbers.
