Hi @rsr

Please try this,

Read the excel and Store in datatable. Variable name dt

Use for each row

Inside for each put an if activity and condition will be row(“columnname”). tostring.length = 16

In then part of if activity put another if activity and in condition give row(“columnname”).tostring.substring(11,2) = 99

In then part put log message and give row(“columnname”). tostring and in else give no

Do same like that for else part of first if condition…

row(“columnname”).tostring.substring(9,2) = 99 - it will search for 9th and 10th position

we can do with regex:
and substring

Hi @prasath_S , its not working. Can you check my workflow?

can you share your workflow please…

Did you check my workflow with file?
your flow showing error:
“If: startIndex cannot be larger than length of string.\r\nParameter name: startIndex”,

Is all the number greater that 10 and also did you check the logs how many number and no came…

CurrentRow(“Loan Account”).tostring.substring(9,2) = “99”
(9,2) is it start with 0 or 1 when it will count?

It will start at 10th position and have 2 characters,

If the string is abcdefghijklmno then the result is kl

  1. what is kl?
    2 . 3236540987994661---- here 3 should be 0 or 1 when its counting?
  2. if the number mixed with degit and character then it will works? like 3236HK0987994661

Thank you

  1. Kl is the 10th and 11th postion of the string “abcdefghijklmno”
