    @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 :-)

        @Perlchamp

        [{"
        

        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

                    @Perlchamp ok, went to numbers, SO much easier!!

                    var today_day_month = moment().format("DD.MM")
                    // today would be "30.04"
                    // tomorrow will be "01.05"
                    // loop thru the array of birthday info from file, one 'row' per birthday
                    
                    for(var birthday of birthday_info) {
                         if( (birthday.birth.startsWith(today_day_month)) {
                             // this birthday is for today
                                console.log(" birthday on "+ today_day_month+" is for "+birthday.name);
                         } 
                    }
