QUESTION
I have the below code running twice daily to clean up some imported data from an API. I just need it to remove duplicate rows as the data is sometimes repetitive and it is very long. A big problem is that it will be collecting 4 columns of data over 2300 rows daily for a year, so it will be around 840,000 rows, and close to 4 million cells at some point. Already, with just about a week's worth of data, it is timing out. I originally had this as part of the main code (as you can see in the sample sheet), but I have moved it to its own function in the client's sheet now. Still, it is running far too long (last execution was 316 seconds, so very close to timing out). Any advice on how to speed this up? Here is the code:
...ANSWER
Answered 2020-Nov-10 at 23:22I believe your goal as follows.
- You want to remove the duplicated rows by checking the columns "A" and "B" using Google Apps Script.
- You want to reduce the process cost of your script.
In order to achieve your goal, in this answer, I would like to propose to use the method of removeDuplicates
. When this is reflected to your script, it becomes as follows.

Basically, I have a .bas file that I am looking to update. Basically the script requires some manual configuration and I don't want my team to need to reconfigure the script every time they run it. What I would like to do is have a tag like this
...ANSWER
Answered 2019-Dec-10 at 14:58You need to make sure you read the whole files in with newlines, which is possible with the -Raw
option passed to Get-Content
.
Then, .
does not match a newline char by default, hence you need to use a (?s)
inline DOTALL (or "singleline") option.
Also, if your dynamic content contains something like $2
you may get an exception since this is a backreference to Group 2 that is missing from your pattern. You need to process the replacement string by doubling each $
in it.
QUESTION
Hi i have a app that takes a list of files and searches each file for all the images referenced within each file. When the list is finished I sort and remove duplicates from the list then copy each item/image to a new folder. It works, but barely. I takes hours for the copying to occur on as little as 500 files. Doing the copying in windows explorer if faster, and that defeats the purpose of the application. I don't know how to streamline it better. Your inputs would be greatly appreciated.
...ANSWER
Answered 2019-Aug-26 at 16:11I would change something in your code to avoid the constant writing to a file at each loop and the necessity to have two loops nested.
This is a stripped down version of your GetFiles intended to highlight my points:
QUESTION
I am trying to remove the duplicates from a list of double arrays. I would like to keep the first instance of the duplicate but remove any found after.
Here is my code:
...ANSWER
Answered 2019-May-27 at 13:52Since you've stated that array will always be size of 2, I suggest you to use different data type. For example, tuple would be more appropriate, because these are actually pairs of values.
For example, you could define a collection of pairs:
List<(double, double)> pairs = new List<(double, double)>(); //C# 7.1+
List> pairsCollection = new List>(); // C# 7 or less
Seed it in this manner:
QUESTION
I'm working on a data manipulation program, and I'm almost done. I've got the duplicate detection algorithm working, and I have a list of all items including duplicates, and a list of duplicates.
I want to go through the list of items, filter by the duplicates list, and remove all but the first of the duplicates. I've tried it like this, but it doesn't actually remove the records from the array.
...ANSWER
Answered 2018-Jul-17 at 17:48I would do something like this:
QUESTION
function removeDupes() {
var out = [],
obj = {};
for (x = 0; x < intArray.length; x++) {
obj[intArray[x]] = 1;
}
for (x in obj) {
out.push(x);
}
return out;
}
...ANSWER
Answered 2017-May-22 at 14:21someObject["somePropertyName"]
is how you access the property of an object. (You can also use someObject.somePropertyName
but only if the property name is a valid identifier).
The syntax has nothing specifically to do with arrays.
Arrays are just a type of object with a bunch of methods that treat property names that are integer numbers in special ways.
(Numbers are not valid identifiers so you must use the square bracket syntax to access properties with names that are numbers).
QUESTION
I have a Module with several Subs in it. Something like this:
...ANSWER
Answered 2017-Mar-16 at 23:18VBA cleans up a lot of "loose ends" when it completes running a VBA program / macro. For one thing, it returns any memory used by the program. If you comment out the call to RemoveDupes, the program will end after sortData, and this clean up process will take place. Then you run RemoveDupes manually, using a clean slate.
Check to see if in the first two subs, you create many/large collections or other objects that don't get set to Nothing at the end of the sub. I think they would have to be declared in the top of the module, before the code for any Sub or Function.
