      @Perlchamp welcome to the fun

      its really month and day… year you would only want to know for big event things… 18, 21, 30, 40,50, …

      so, I would reorg the data as a hash (object) by date, and list [array] of people [‘Stan Smith’, ‘Joe Anyone’]

      birthdays = {}
      u can use the moment() object to get the month/day, or had code to extract the part of the date month/day,
      birthdays[birth_date][‘names’] = [‘Stan Smith’, ‘Joe Anyone’]
      then send the birthdays object up to modulename.js

      modulename.js in getDom()
      it uses moment().format(‘MMDD’) or (‘DDMM’) (same as node_helper did)
      then
      if( this.birthdays[date] !=undefined) // if there is something for today
      then can add the names in a for loop to the html to display

      and if you use moment() in modulename, u can add/subtract to look ahead, and it will format the right month/day,
      and u can get the day name

      today,
      tomorrow
      saturday
      sunday,
      next week…

        uff, now first i have to read some papers for understanding that stuff …
        in the moment i only can see the output of the json-object via terminal. i don’t have them saved in an array or string. i wanted to use a async-method (by await), but it seems that this is the wrong way (error-messages) …
        i think to put the data first in an array couldn’t be wrong so far ?

         {
            Geburtsmonat: 'März',
            Geburtstag: '7',
            Geburtsjahr: '1972',
            Name: 'Julia Ützglütz'
          },
        {
        ...
        }
        
        

        could it ?

          @Perlchamp should already be an array of row(of column name/value pairs)…

          the JSON class has stringify(object) to convert json to text,

          console.log(JSON.stringify(results of convert))

          also has parse (from text form of json to object)

            ok, now i have a dictionary (is that called though?) - always 4 columns (i will change that, if i read how to put it all in an array. in the moment i just have the output via console …)

            [{"Geburtsmonat":"Januar","Geburtstag":"3","Geburtsjahr":"1940","Name":"Renate Stögger"},{...},{...}]
            

            but i’m on the right way, thanks again :-)

              array [ of objects {}, {}. {} ]
              the names of the object elements are the names of the columns (row 1 in the csv)

                @sdetweil said in read csv-data and put it in an array:

                the names of the object elements are the names of the columns (row 1 in the csv)

                yes i know.
                i thought it’s an dictionairy and not an array. but it’s ok …

                  @Perlchamp the [ (open square bracket) means array in javascript

                  the array can be numbers, strings or objects (open squiggly bracket)

                    status:
                    i wanted to “play” with the jsonArray, but things like jsonArray[“birth”][0] or jsonArray.birth[3] will not be accepted, although it is listed in many websites … i try and try and read and read, but in the moment no solution. the parameter “length” count the number of letters and numbers ?
                    then I will have to deal with moment () first …

                      @Perlchamp u did not show the code, so I will call the output of the csvtojson() birthday_info

                      example of how to navigate the json data

                      in module there would be no ‘var’ cause of the way the modulename and helper are packaged inside object

                      // if not using numbers but month names 
                      // make indexOf return 1-12, not 0-11 (dummy thing never matched 1st)
                      // fix this with your language abbreviations
                      // usually in lower case, then always convert data to lowercase for compare to prevent having users remember to get the case right
                      var months= ["0", "jan","feb","mar"...."dec"]
                      
                      var today_day_month = moment().format("DDMM")
                      // today would be "3004"
                      // tomorrow will be "0105"
                      // loop thru the array of birthday info from file, one 'row' per birthday
                      
                      for(var birthday of birthday_info) {
                           // get the day/month string in numbers to match output of moment()
                           // get the last 2 chars of the day and month with a 0 on front.. 01-09, 12, ---31, or 01-09,10/11/12
                           if( ("0"+birthday.Geburtstag).subString(-2)+("0"+months.indexOf(birthday.Geburtsmonat.toLowerCase())).subString(-2) 
                                               == today_month_day) {
                               // this birthday is for today
                                  condole.log(" birthday on "+ today_day _month+" is for "+birthday.Name);
                           } 
                      }
                      
                      ``

                        i didn’t post the code, because it only was a status-info …
                        but here is the code. i think i will first try alone. if there any questions i will post them.
                        here is my array:

                        [{"birth":"12.09.1967", "name":"Otto Billing"},{...}]
                        

                        many thanks in advance
