QUESTION
I have a method that converts csv to json data:
Here is the code:
...ANSWER
Answered 2021-May-13 at 13:59Your problem is with line-endings, not Angular. Different operating systems have different standards on how to encode the "new line" character; this is a common annoying issue when parsing human-readable strings (such as the CSV format). You read about this in detail on Wikipedia, for example.
The \r
you're getting probably means that the original file had \n\r
for line endings. When you do a split at \n
, the right-hand part will retain the leading \r
. To remove the \r
as well, you'll have to split by \n\r
instead, treating the whole group as a new line.

QUESTION
The first API request successfully send a response. However, when I do another GET request the error "write after end" is given.
When I turn off .pipe(addThing)
then it does work on consecutive calls.
Is the through2-map function ending the connection or response somehow?
...ANSWER
Answered 2020-Mar-02 at 11:36After reading "Error: write after end" with csv-write-stream I noticed that the problem might be that the variable addThing
is not created new on every consecutive call.
It was allocated in memory.
So the solution:
QUESTION
I learned how to write JSON
object from local csv
file. However, I am designing a simple check-in web application with javascript and I want to update json file locally. I asked SO
community how to update json object in javascript and people suggests using NodeJS
express framework which is totally new and complicated to me. I am thinking what if I can simply update json object locally, and want to learn efficient javascript solution on this task.
Basically I have local mother json file use it as simple database to check the record, and I have source csv
file that can be written as new json object, so my program want to compare the record in new json object from mother json file.
here is what I tried:
in this script, I am able to write and print out JSON
object on the console from local csv
file, and I am able to check whether manually entered record are in json object or not.

QUESTION
I am trying to create a dataframe from RDD in order to be able to write to a json with following format A sample json is as shown below(expected output)
"1234":[ { loc:'abc', cost1:1.234, cost2:2.3445 }, { loc:'www', cost1:1.534, cost2:6.3445 } ]
I am able to generate the json with cost1 and cost2 in String format. But I want cost1 and cost2 to be double. I am getting error while creating data frame from rdd using schema defined. Somehow the data is being considered as String instead of double. Can someone help me to get this right? Below is my scala code of my sample implementation
...ANSWER
Answered 2018-Sep-12 at 14:31I would suggest you to stay with dataset or dataframe by using inbult functions as they are optimized version of rdds.
So you can do the following to achieve your requirement
QUESTION
My algorithm for converting CSV to JSON data works but when I click "Download JSON" it gives me a CSV file. Does anyone know what the issue is?
Also, the "convert to CSV" button is not outputting anything!
You don't need to pay attention to the Highcharts code even though I included it.
Does anyone know how to fix this? The code is here (some of the code belongs to Sturtevant from JSFiddle. Credits to him):
