Title: Cool Hand Luke

Format: VHS

I already have file data in string format.
Somehow I must convert it to JSON
I've to try split in this way
file.buffer.toString().split('\n')
But how should I move on?

You can use this npm library.
https://www.npmjs.com/package/export-from-json
Also we can get other formats csv, txt, xls etc.
You can check my usage example: https://github.com/devStack03/node-csv-json-export

Split on the newline character, split each of those strings by the colon symbol. Use reduce and create a new object in the accumulator a when there is a blank line, otherwise set properties in the most recent object in the accumulator for every non-empty [key,value] pair encountered.
const s = `Title: Blazing Saddles
Release Year: 1974
Format: VHS
Stars: Mel Brooks, Clevon Little, Harvey Korman, Gene Wilder, Slim Pickens, Madeline Kahn

console.log(s.split('\n').map(i=>i.split(': ')).reduce((a,[k,v]) =>
(!v && a.push({}) || (a[a.length-1][k]=v), a), [{}]))

Strategy to Loop Through 2D Array from Google Sheets To Create Entry for Each Date and ID

I have a Google Sheet that contains data I need to manipulate. It is essentially a list of assignments by student. The original columns are:
Name, ID, Assignment 1, Assignment 2, Assignment 3, Assignment 4, Date, Overall Grade
Using existing code, I am concatenating the Assignments into a single field and creating an array with these columns:
ID, Name, Assignments, Date, Overall Grade
The resulting array looks like this:
[ [ '1234',
'Santa Claus',
'US History Chapter 1.1, , , ',
Fri Nov 18 2022 00:00:00 GMT-0800 (Pacific Standard Time),
'B+' ],
[ '1234',
'Santa Claus',
'US History Chapter 2.1, US History Chapter 1.1, , ',
Thu Nov 17 2022 00:00:00 GMT-0800 (Pacific Standard Time),
'B' ],
[ '12222',
'Mary Poppins',
'US History Chapter 8, , , ',
Fri Nov 18 2022 00:00:00 GMT-0800 (Pacific Standard Time),
'A' ]]
On a separate sheet I have a list of dates. What I want is to have a line for every single student and date combination and the assignment data if it exists. E.g. If the dates are Nov 17, Nov 18, and Nov19 and there are 2 students with data in the list, there would be 6 total entries sorted by student then by date. For the Assignments column, there would only be data if there was an assignment entered for that date and that student. Otherwise it would be blank. For example:
ID
Name
Assignments
Date
Grade
1234
Santa Claus
Chapter 2.1, US History Chapter 1.1
Nov17
B
1234
Santa Claus
US History Chapter 1.1
Nov18
B+
1234
Santa Claus
Nov19
12222
Mary Poppins
Nov17
12222
Mary Poppins
US History Chapter 8
Nov 18
A
12222
Mary Poppins
Nov19
What I think is needed is something like this:
Get unique list of all student IDs from the array
Get list of dates from the sheet
Use a nested loop to go through each date and each student to create the lines. If there is a match for the assignment data, add it, if not, leave that blank.
I'm just not sure how to manipulate the array to do something like that. How would I approach this?

Although, unfortunately, I cannot know your actual array, from your showing sample array and a sample table, how about the following sample script?
Sample script:
const array = [,,,]; // Please set your array.
const res = Object.entries(array.reduce((o, e) => (o[e[0]] = o[e[0]] ? [...o[e[0]], e] : [e], o), {}))
.sort(([a], [b]) => Number(a) > Number(b) ? 1 : -1)
.flatMap(([, v]) => v.sort((a, b) => a[3].getTime() > b[3].getTime() ? 1 : -1));
console.log(res)
In this sample script, first, an object is created by checking the column "A". And, sort the array by the column "A". And, for each element, sort the column "D". And, all values are merged as a 2-dimensional array.
Note:
If this sample script doesn't return your exected values, can you provide the detailed sample input values and the sample output values? By this, I would like to confirm it.
References:
reduce()
sort()

Using regular expression to capture the name of the speaker and the comment

I would like to capture the name of the speaker and the comment that was made. I've tried using several different variations of ([-]{5,}\s\S+), but this doesn't seem to do the tricky. Ideally, I would like to end up with the following:
var data = [
{
name: "Operator",
comment: "Ladies and gentlemen, thank you for standing by. Welcome to the 3M First Quarter Earnings Conference Call. (Operator Instructions) As a reminder, this conference is being recorded, Thursday, April 25, 2019. I would now like to turn the call over to Bruce Jermeland, Vice President of Investor Relations at 3M."
},
{
name: "Bruce Jermeland, 3M Company - Director of IR",
comment: "Thank you, and good morning, everyone. Welcome to our first quarter 2019 business review.

You could use a capturing group and for the match of the speaker use a character class and specify what characters you would allow for the name and repeat that with a space in between.
Then match the line with only hyphens followed by using a second capturing group matching the following content until you encounter the next line that starts with a hyphen. (Or multiple if you want to make it more specific.
^[ \t]*(\w+(?:[ \t]+[\w,-]+)*)[\t ]+\[\d+\]\r?\n-+\s+((?:(?:\r?\n)?(?!-).*)*)
Explanation
^ Start of string
[ \t]* Match 0+ tabs/spaces
( Capture group 1
\w+(?:[ \t]+[\w,-]+)* Match 1+ word char and repeat 0+ times matching 1+ tabs/spaces and a character class where you could specify what you would allow to match.
) Close group 1
[\t ]+\[\d+\] Match 1+ tabs/spaces, the 1+ digits between [..]
\r?\n-+\s+ Match newline, 1+ times a hyphen followed by 1+ times a whitespace char (which will also match the prepended spaces before the start of the comment)
( Capture group 2
(?: Non capturing group
(?:\r?\n)?(?!-).* Match optional newline, assert what is on the right is not a hyphen, then match the rest of the line.

A regex like /-{5,}(.*?)-{5,}(.*?)(?:-{5}|$)/gs will capture both the speaker and the spoken text (it will only break if the spoken text / speaker name contain more then 4 dashes after each other -----)
regex101 demo
Explanation:
-{5,} will match the first row of ----s, before the speaker name
(.*?) captures the speaker name
-{5,} matches the second row of ----s, the separator between speaker <-> spoken text
(.*?) captures the spoken text
(?:-{5}|$) matches either the end of the file or five dashes -----. (this leaves enough dashes for the first part of this regex to match again for the next speaker)
Example:
function sanitizeName(name) {
// trim it and remove the " [12]" after the name
return name.replace(/\s*\[\d+\]\s*$/, '').trim();
}
function parseConversation(text) {
let regex = /-{5,}(.*?)-{5,}(.*?)(?:-{5}|$)/gs;

Parsing a JSON string in node js?

I am trying to send a JSON string and parse it in my server side in node js.
I want to extract specific values like title but for some reason I get undefined when I try to parse it.
This is what I tried so far.
Home.ejs
$.each(item, function(key, value)
{
var s = JSON.stringify(value);
s = s.replace(/^\s+|\s+$/g,'');
info.push(s);
});
console.log("info",info);
if (response.status == 'ok') {
$.ajax({
type: 'POST',
url: '/home',
data: JSON.stringify(info),
success: function (data) {
},
error: function (data) {
console.log('error');
console.log(data)
}
});
}
This is what it prints out in the console.

I want to extract the title value but for some reason I keep getting undefined when I try req.body.title.

It looks like you are having an issue because you are using JSON.stringify on each array element and then using JSON.stringify on the compiled array.
You should get the expected outcome by stringifying the whole array without stringifying each part. i.e. in your case just stringify the item
$.ajax({
type: 'POST',
url: '/home',
data: JSON.stringify(item),
success: function (data) {
}

My problem: my regex matches from the wrong starting point when certain lines are duplicated in the source text. See screenshot below taken from RegexBuddy's test panel for a better explanation.
How can I change my regex to match starting at the point indicated?

I solved that problem with this:
subject.match(/\s\([A-Z]{3}\)[\w\s]+\([A-Z]{3}\).*\n(?:.{3,}\n)*.*\([A-Z]\)/)
Just completed the first line with non newline elements (0 or more), then matched a newline (just 1), and then matched all lines with length of 3 or more, untill last (had to fill it too).
PD: There's a non capturing group there, harmless.

One of the problems of your regex is that you allowed anything, including the newlines, before the second right parenthesis. That's causing the ending match to the string "(L)". If you can include in your requirements that at least three lines of text are needed to start a match, then the following may work for you:
subject.match(/\s\([A-Z]{3}\)[^\r\n]+\([A-Z]{3}\)([^\r\n]+[\r\n]){3,}/);

How can I group the yAxis of a HighStock Chart by Month Only Using (Millisecond) Time-Stamps?

I have a database, where I am getting time-stamps (millisecond) along with price values and trying to plot them on a "HighStock" chart.
I was told to, instead of just letting the exact date show up on the y-axis, have the y-axis show only on a month-by-month basis. The problem is that I have an array of arrays (the format, and the only format I'm aware of, that HighStock accepts) with time-stamps which end up being interpreted by exact date (as I would expect).
I thought about just modifying the time-stamps myself based on month (I already have JavaScript functions that can convert time-stamps to dates and vice versa), but then I would get something like Monday, Jul 1, 2013 -- Thursday, Aug 1, 2013 etc. Of course, the Jul 1 or Aug 1 could be converted to whatever date I grouped by in the time-stamp, but I really would need to take that out entirely and have it say just Jul and Aug. I'm sure this is possible, given the never-ending plethora of options HighCharts/HighStock has, but I am out of options on where to look.
With the help of the following sites:
http://api.highcharts.com/highcharts
http://api.highcharts.com/highstock
And trying things myself, I have learned a bit about what some of the options do, but I am no closer to my original goal.
I have looked in plotOptions, xAxis, and others (where I would think they might be) but I am on the verge of giving up. The documentation on these sites are very helpful, but it is not always clear what they do, or what syntax they expect.
Whether there's an easy way to this with HighCharts/HighStock options using the original time-stamps alone, or whether I need to convert every time-stamp to a date, compare months while adding values together, then re-converting back into a time-stamp, and finding a chart option which omits all but the month and year, I have to get this done. Any help is greatly appreciated.

Here's an example from the Highcharts API Reference page.
If you have categories like this, for example:
categories: ['Jan 1', 'Feb 1', 'Mar 1', 'Apr 1', 'May 1', 'Jun 1', 'Jul 1', 'Aug 1', 'Sep 1', 'Oct 1', 'Nov 1', 'Dec 1']
You can use this type of config for the xAxis label:
xAxis: {
categories: ['Jan 1', 'Feb 1', 'Mar 1', 'Apr 1', 'May 1', 'Jun 1', 'Jul 1', 'Aug 1', 'Sep 1', 'Oct 1', 'Nov 1', 'Dec 1'],
labels: {
formatter: function () {
return this.value.substring(0,3); // - formatted return value
//return this.value; // - default return value
}
}
},
Here's a Fiddle that you can mess around with to show you exactly how it works: Click Here.
