Logic problem?

Daz474 — Thu, 08 May 2025 08:47:49 GMT

I wonder if anyone can come up with a simple solution to the following problem. I am sure its easy but it takes me forever.

My data has only two fields - Account Code and Description I do not have any reference key or date field. There are millions of transactions and in only one of them there is a Smiley Face character in the text. This character breaks the load and I cannot get any data. I need to isolate which Account Code it belongs to.

I could try loading a range of account codes at a time and if it does not fail i know that I can exclude this range of Account Codes. but there are just too many for that. I cant do a between because it is alpha-numeric. Or is there a way to do that?

Additionaly, I want to make sure that I capture all of these characters in the case there are several at a time.

Daz474 Hi!

In Power Query you can add a custom column to select only safe characters:

= Table.AddColumn(#"Previous Step", "HasSpecialChar", each Text.Length(Text.Select([Description], {"A".."Z","a".."z","0".."9"," ",".","-",",","/"})) <> Text.Length([Description]))

Then remove the original column with unsafe characters.

Hi Daz474,

Thank you for reaching out in Microsoft Community Forum.

Please follow below steps to resolve the issue;

1.In Power Query, you can filter out records containing specific characters. This will allow you to detect any rows with unusual or special characters, like the Smiley Face.

2.You could create a custom column that checks for non-standard characters in the Description field.

3.Add a custom column with a function to identify the presence of a Smiley Face (😊) or any other non-standard characters.

let
Source = YourSourceTable,
AddCustomColumn = Table.AddColumn(Source, "HasSmiley", each if Text.Contains([Description], "😊") then "Yes" else "No"),
FilteredRows = Table.SelectRows(AddCustomColumn, each [HasSmiley] = "Yes")
in
FilteredRows

Thanks for the suggestion. This won't work though because if there is a special character in the data load, it breaks it and nothing loads. I need to find the character without loading it.

Sorry for the delay!

This doesn't work because if the character is in the load then it won't load anything. I need to find the characters without loading it.

Ok, now it's clearer. So try to Load as Binary First, then Inspect Lines Before Parsing.

let
Source = File.Contents("C:\YourFile.csv"),
Lines = Lines.FromBinary(Source, null, null),
TableFromList = Table.FromList(Lines, Splitter.SplitByNothing(), {"Line"}),
AddCheck = Table.AddColumn(TableFromList, "HasNonAscii", each List.AnyTrue(List.Transform(Text.ToList([Line]), each Character.ToNumber(_) > 127)))
in
AddCheck

Hi Daz474,

Thank you for reaching out in Microsoft Community Forum.

Since the presence of a special character (like a smiley face) breaks the data load completely, the safest approach is to analyze the file in raw binary format before any parsing happens in Power BI.

Please follow these steps to safely identify the problematic row:

1.Use File.Contents to load the file as raw binary instead of as a table. This prevents Power BI from trying to parse corrupted characters.

2.Convert the binary into a list of lines using Lines.FromBinary.

3.Convert the list of lines into a table so you can inspect each one.

4.Add a column to flag lines that contain non-standard (non-ASCII) characters, such as emojis or symbols.

5.Optionally filter the table to only show the problematic rows, helping you isolate the account code.
