Hi,

All right. I also think sensitive data should not be uploaded.

I decoded the above base64 data to byte array and it’s 0x2C,0x3C,0x07,0x01…
If your string consists of ASCII characters, it does not match your string because there is speciall character 0x07, 0x01 etc.

So can you try to review input string and logic for convert to Base64 in the python script?

Hi,

System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(base64String))

Your expression seems good if it’s UTF-8 encoding.

I have a value 2456.856787 in this value i need only 2456.85 remaining value we need remove after dot i need only two digits .

The following expression will work, for example.

System.Text.RegularExpressions.Regex.Match(yourString,"\d+\.\d{2}")

Do you need to encode to or decode from base64?

Using Convert.ToBase64String(), I have a base64 string of binary file (.tif) and would like to create a PDF from it. How do I do that?
