read csv-data and put it in an array

Perlchamp

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)

Perlchamp

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)

Perlchamp

@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);
     } 
}
