Fixed Width Parser

Overview

This Snap reads binary data from its input view, extracts field values based on the field configuration, and writes document data to its output view.

Snap views

Type Description Examples of upstream and downstream Snaps
Input This Snap has exactly one binary input view, where it gets the binary data to be parsed for fixed length columns. JSON Generator
Output This Snap has exactly one document output view, where it provides a document data stream. Each document contains the extracted field values. All fields in the document data are of string-type. The Mapper (Data) Snap can be used to transform the data type from string-type to required type. Group By Fields

Snap settings

Legend:
  • Expression icon (): Allows using pipeline parameters to set field values dynamically (if enabled). SnapLogic Expressions are not supported. If disabled, you can provide a static value.
  • SnapGPT (): Generates SnapLogic Expressions based on natural language using SnapGPT. Learn more.
  • Suggestion icon (): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
  • Upload : Uploads files. Learn more.

Default value: 0

Example: 2
Line separator String/Expression The character used to separate lines in the input. Leave empty to separate lines using new line character or specify the character used for separating lines.

Default value: \n

Example: \n
Field configuration Details to be filled for each field that is required in the output.
Column names String/Expression Required. Column names to be used as headers for the extracted values.

Default value: [None]

Example: First Name; Last Name
Start position String/Expression Required. Starting position of each column to be used while extracting field values.

Trim column data String/Expression Required. If removal of leading and trailing spaces is required on the extracted data

Default value: False
Ignore Lines This is a table property allows user to ignore lines in the input document satisfying the provided condition.

Select one of the three modes in which the Snap executes.

  • Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution during Pipeline runtime.
  • Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Default value: Execute only

Example: Validate & Execute
