I'm looking to export a large quantity of saved Security log files (.evtx) to text or CSV format. I found wevtutil but that only seems to be able to convert .evt to .evtx when dealing with saved log files:
event log convert into evtx to csv

In the end I went with Log Parser to convert to CSV and then [System.IO.File]::ReadLines($filename) to search through the text. An 800MB .evtx file can be converted in about 2 min 30 sec and then reading through the file takes about 2 mins. Possibly it could be quicker exporting to XML or into a database but it will do for me with the amount of time I had to spend.
As far as I remember, LogParser was not able to extract all event information (I mean both System and EventData that you can see in the xml view for each event in the EventViewer). Therefore, I went with powershell. My script works well, but is very slow: it needs about 80 seconds to convert 10 Mb .evtx file...
I needed to bulk convert a bunch of .evtx to .txt files - I did end up getting Log Parser to convert to .csv (which i can then rename .txt), but the easiest way (and only uses native windows tools) was to use wevtutil.
Event Log Explorer can export events into Excel, HTML, CSV and PDF files. The export is implemented as an option of user interface and it can be scheduled using internal Event Log Explorer scheduler. Some time ago, I wrote a couple of articles how to schedule export of events into Excel: -event-logs-with-windows-powershell/
Note: An .evtx file must be exported with the Display Information so that events from sources can be read on other machines. Failure to include the Display Information may delay the investigation of the support case.
Now, the logs are ingested and parsed and it's already a start (I get proper sourcetypes and everything). However, they do not go through the Windows' app normalizing process, e.g. events don't get populated with the "EventID" field, user names are not parsed into SubjectUserName and TargetUserName fields, things like that.
Hey, Scripting Guy! I have been using a scheduled job and a Windows PowerShell script to archive our event logs to .evt files. When I need to check something, I need to import the .evtx file in to Event Viewer so that I can search the file. This is a bit cumbersome, and I would like to find a better way to do this. What I really wish is that I could query the .evtx file in the same way that I query a live event log. I think I can use LogParser to query the .evtx file, but I do not know what is up with that. It is more than six years old, and I hate to be dependent on something that is not in the operating system.
This particular view into the event log is not too bad, because I can easily tell that my connection to the Microsoft Exchange Server lost connection on 1/7/2011 for a minute and 21 seconds (by subtracting the amount of time between connection lost and connection restored).
As the script currently stands, the script does not accept input parameters for the start time and end time or for the path to the stored logs, but that is an easy change to make. The Try/Catch block is required because an error is generated when an event log does not return any matching records. It is a non-terminating error, however, so I needed to specify the ErrorAction (EA is the parameter alias) of stop to cause the script to move into the catch block.
Below you will find the PowerShell script that you can use after customizing to your environment. You will need to copy and paste this script into a CVE-2020-1472EventReader.ps1 file on the device you are using to process the events.
Unlike other event logs, such as the UNIX syslog, Windows Event Log is not stored as a plain text file but in a proprietary binary format.Therefore, it is impossible to view the logs in a text editor or send them as syslog messages while retaining their original format.However, the raw event data can be translated into XML using the Windows Event Log API.
You can process a log file with the File directive, in which case im_msvistalog will read all events from the .evtx file.This method is intended primarily for forensics, for example, using the nxlog-processor to process historical data.
Most SIEM solutions accept logs in JSON format to preserve all event log fields.The xm_json module provides the to_json() procedure to convert data to JSON format.See the examples in the NXLog Enterprise Edition Reference Manual to better understand how NXLog parses and converts JSON.
NOTE: You can save your log file as an Event File (.evtx), an XML file (.xml), a tab-delimited file (.txt), or a comma-separated file (.csv). The only file type that you can import again into the Event Viewer is the .evtx type. The other types allow you to view your log data outside of the Event Viewer, but the files cannot be imported back into the Event Viewer.
If you selected the .evtx file type, the Display Information dialog box displays. If you want to be able to import the log data into the Event Viewer on another computer, you may need to include display information with the exported log file. Select the Display information for these languages radio button. If you need another language, select the Show all available languages check box and select the check box for your desired language, if available. Click OK.
It will first check every file inside the logs folder for .evtx extension and run evtx_dump.py on everyfile thereafter storing the .xml in a new folder, i.e., parsed-evtx. If it is not able to parsea file into XML due to some error, the filename will get saved in conversion.log.
Second, you can copy the below reg script into Notepad, save it using the .reg extension, and merge it into your registry. When you do this and restart your system, you'll be able to right-click on an .evt file and select a "Convert to evtx" option from the shortcut menu.
LINE93: $Events = Get-WinEvent @Path=$evtxfile;Id=2889 Searching inside the evtx file for event id 2889 and get them in variable $EventsAfter this variable is available we need to have a look on every single event with another foreach loop.
As Windows auditing subsystem is complex, this article focuses on part of it: the Event Logger. In modern Windows systems audit events are saved to files with extension .evtx (Windows XML Event Log). These files are stored in C:\Windows\System32\winevt\Logs location. As the log files are saved in binary XML format, we need specialized libraries to open and convert them to readable format.
As an input It takes the path to folder with multiple .evtx files from various computers. The output will be segregated based on computer names present in log files. If you are in possession of logs from backup or VSS, you should also provide them as output events will be deduplicated.
Lets say you have many exported EventLog (evt/evtx) files, and need to search for specific event entries on all of them. how do you do it?Yes. Of course you can use Microsoft Log Parser 2.2 but then you have to write the cumbersome query yourself. bummer.
So if you want to read evt files on Windows Vista, 7 or Server 2008, you should convert them old-school EventLog files into the shiny new format. You can accomplish this using any of the two methods described below:
Windows generates log data during the course of its operations. The Windows Event Log service handles nearly all of this communication. It gathers log data that installed applications, services, and system processes publish and places the log data into event log channels. Programs such as Microsoft Event Viewer subscribe to these log channels to display events that have occurred on the system.
thanks for this..it works brilliant. any idea how to convert the cs-uri-stem to all the one case before you import it into a SQL Server database. I have tried some combinations but the syntax fails. I wonder if its possible. thanks
All logs post-Windows Vista save as *.evtx files instead of an older *.evt format. The property IsClassicLog states whether the log events are defined in a Message File, *.mc, format or in a manifest, *.xml, format.
Amazon Kinesis Agent for Microsoft Windows streams logs, events, and metrics to AWS services.
