# CSV Parser ### Overview CSV parser is a filter that helps read and parse tabular data stored in CSV (Comma-Seperated Values) format into another data structure, usually a JSON logs structure. *** ### Configure CSV parser To create a CSV parser configuration, follow the instructions below: 1. In the **Processor information** section , enter general information for a processor according to the instructions in [Processor](https://docs-vngcloud-vn.translate.goog/vng-cloud-document/v/vn/vmonitor/dashboards/logs/lam-viec-voi-log-pipeline/processor) . In this content, you will choose **Processor type** as **CSV Parser** . 2. In the **Parsing rule** section , enter the following information: * Enter **Source field** : field containing logs that will need to be parsed. Filed logs need to be in CSV log format. * Enter **the Target field** : the field will be overwritten in the destination log project, normally you will not need to enter this information * Enter **Columns:** enter the column names in the corresponding order on **the Source field,** the system will map these column names as the corresponding field names on **the Destination field.** * **Separator** : enter the separator character between corresponding columns on **the Source field,** the system default is the character ",". For example: | **Source log project** | **Destination log project** | **Message (field logs mà chúng tôi thực hiện parser)** | **Columns** | **Seperator** | **Kết quả parser** | | ---------------------- | --------------------------- | ------------------------------------------------------ | ------------------------------- | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | webserver | webserver-parse | Message (field logs mà chúng tôi thực hiện parser) | time,action,ip\_address,message | , |

"time": "2020-09-01 10:35:25",
"action": "RESTART",
"ip\_address": "192.168.1.3",
"message": "System restarts"
}

## Store and reuse Parsing rules * You can store a parsing rule by checking **Save this rule** , then entering a memorable name for the parsing rule you want to store. The mnemonic name has a minimum length of 5 characters, a maximum length of 255 characters and can only include upper and lower case letters (az, AZ), numbers (0-9), and dots (.), space ( ), underscore (\_), hyphen (-), and the @ character. * After the parsing rule has been stored, in subsequent processor creations you can reuse this rule by selecting **Rule presets** in the Pasing rule section. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
