Convert Text Files to Fixed-Width Format Automatically
Advanced ETL Processor is Windows software for converting Text to Fixed Width File without writing scripts. Map, validate, and transform fields visually, then run the conversion or schedule it to repeat.
Need to convert text files to fixed-width format without scripting? Advanced ETL Processor reformats CSV, tab-delimited, and other structured files into column-aligned fixed-width output. It keeps field positions predictable, which is exactly what mainframes and older systems tend to demand.
Text to Fixed Width File conversion workflow
Keep the conversion in one reusable package so field mapping, validation, output settings, and run history do not depend on a manual export checklist.
- Read: Select the Text input and the files or records to process.
- Map: Match source fields to the required Fixed Width File structure and apply transformations.
- Validate and write: Check data types, required values, formats, and rejected rows before creating the output.
- Schedule and review: Run once for testing, then schedule repeat work and use the log to investigate failures.

What Is a Fixed Width File?
Fixed-width files store data in plain text where each column has a defined length and position. They are widely used in financial, insurance, mainframe, and EDI systems where strict formatting is required. Padding, alignment, and position matter - and manual formatting is error-prone.
Why Use Advanced ETL Processor?
- No scripting or manual formatting required
- Visually define column widths and alignment
- Supports all input formats: CSV, tab, fixed, and custom
- Flexible padding options: space, zero, custom characters
- Automated job scheduling and error logging included
How to Convert Text to Fixed Width Format
- Launch Advanced ETL Processor
- Create a Source Directory Connection
Select the folder where your original files (e.g. CSV or TXT) are located. - Create a New Transformation
Right-click your transformation group and choose New. - Configure the Text Reader
- Set file mask (e.g.
*.csv) - Define delimiter, header row, and encoding settings
- Set file mask (e.g.
- Configure the Fixed Width Writer
- Specify column widths and field order
- Set alignment (left, right) and padding characters
- Choose output folder and filename rules
- Map and Transform Fields
- Use drag-and-drop to reorder fields
- Apply trimming, formatting, or conditional logic
- Run the Transformation
- Click Execute to generate your fixed-width file
- Open output to verify alignment and format
- Automate the Workflow
- Schedule regular conversions
- Trigger based on file arrival, time, or system events

FAQ
Can Advanced ETL Processor convert Text to Fixed Width File?
Yes. Advanced ETL Processor can convert Text to Fixed Width File, validate the data, and log the workflow run.
Do I need to write a script?
No scripting is required for routine conversion, validation, scheduling, and logging. Use scripts only when the rule genuinely needs custom code.
Can I convert multiple Text files at once?
Yes. Point the file reader at a folder and use a file mask so matching Text files are processed in one package.
Can the Fixed Width File output be created on a schedule?
Yes. The Enterprise edition can run the package on a schedule or as part of a larger ETL process, then write the Fixed Width File output with the same naming and validation rules each time.
What should I check before the first production run?
Check headers, data types, date formats, decimal separators, encodings, empty values, and output file naming.
When should I not automate this conversion yet?
Do not automate it until source columns, data types, output naming, and error handling are clear. Conversion repeats rules; it does not repair vague ones.
Can I try it before buying?
Yes. Download the fully functional 30-day trial and build one small conversion package first.
