Hi, I have a scenario where I will be reading csv file, from that i have extract column value(s) and assign to custom attribute(s). From custom attributes I have to form a json file. I have gone through the extractText processor we need to pass regular expression to get the text, not quite understanding with that, is there any better and easy way to get above requirement? sample csv file. ID Description Status project 8075 John Done xyz100 Extract ID and project and create custom attributes like projectID=ID and modelProject=project. Thanks --Murali

Hi All,
I have a scenario where I will get a number of records from csv file, the task is to read the csv and split each record as one file and save the each file and sheet name with the record name of the 1st column(exclude 1st row as header).
1. What I have done is read the csv file using Getfile,
2. then used splittext processor, to split each record as one csv file by setting property Header line count to 1.
3. then need to extract the 1st record at column1, use that record(2nd row and 2nd column) value as file name and sheet name for the each individual file
Original csv file:
after split the there should two files, one with the name ab123.csv and c35ks.csv and also sheet name also should be changed.
ID
Description
status
ab123
Eldon Base for stackable storage shelf, platinum
ab123.csv
ID
Description
status
c35ks
1.7 Cubic Foot Compact "Cube" Office Refrigerators
c35ks.csv
How to get above out puts after the work flow.

I have a scenario where list of files are coming from previous processor, where for each file, I have to create json file with attributes of the flowfile. In AttributesToJSON processor configuration there is option to extract pipeline attributes and can create json files/object, if we set Include Core Attributes to true, it will read some of the file properties and forms the json file. the out for the above case in my scenario is …
{"fragment.size":"125"
file.group:"root",
file.lastModifiedTime:"2020-12-22T15:09:13+0000",
fragment.identifier:"ee5770ea-8406-400a-a2fd-2362bd706fe0",
fragment.index:"1",
file.creationTime:"2020-12-22T15:09:13+0000",
file.lastAccessTime:"2020-12-22T17:34:22+0000",
segment.original.filename:"Sample-Spreadsheet-10000-rows.csv",
file.owner:"root",
fragment.count:"2",
file.permissions:"rw-r--r--",
text.line.count:"1"}
}
But the files has other properties, like absolute.path, filename, uuid are missing in the above json file.
My requirement is, get the absolute.path, filename and uuid and concatenate absolute.path+/+filename, assign this to custom attribute say filepath:absolute.path+/+filename and also add uuid to json object. so my json file should like { uuid:"file uuid value", filepath:"absolute.path+/+filename" } any inputs to get above form of json file.

The issue is with the missing of square brackets at starting and @ ending .. The working query is .. [{ "$group": { "_id": { "X": "$X", "Y_DT": "$Y_DT", "Z": "$Z" }, "adj": {"$sum": "$adj" }, "bjc": {"$sum": "$bjc" }, "jbc": {"$sum": "$jbc" }, "mnk": {"$sum": "$mnk"} } }]
