    Thanks for this. For some reason, I was always a bit afraid of these type of documents. You helped to really demystify them with this video. Kind thanks!

    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).

    I try to import huge data from some app, the excel file is too small for it as data has 65 mln rows, so I save it as txt file, but when I open it there is some html tags and no data, is it possible to resolve this problem, Please?

    • @macmost
      @macmost  Месяц назад

      Probably. You'd have to work at it. Examine the file, clean it up using various techniques, etc. What do you do depends on what is in the file. It will take skills and hard work.

      You'd either need to import it into an Avery template and work with it there. Or, get some label-printing software that handles it.

    In windows 10, I often make a folder full of movies, or other MP4 files. I do not create a CSV file, but when I list the files in the folder, there is a good CSV file among all these MP4s, listing all of the MP4s. I’m not sure if Windows creates that, or if the downloading software I use creates it. Has anyone else experienced this automatic appearance of a CVS file?

      Just google "convert PDF to CSV"

    • @macmost
      @macmost  Год назад +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.

    It seems rare to find in references, directions on how to represent an EMPTY field within a record. If anyone needs to know, the way to do that is by using 2 adjacent commas. The empty field would be between those, if it were present. For two adjacent empty FIELDS you would use 3 adjacent commas, and so on.

      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.

    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

      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.

    • @macmost
      @macmost  Год назад

      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.

      @@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

      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.

    When someone who's never used anything like that gets a notice to say, put your passwords into csv files and they've all been removed from you by Google; what do you then? There's a box to click for CSV and when I click it, all I get are files from my photo album. No good.
