Find blank cells, duplicate headers, repeated rows and inconsistent row widths.
How to use it
- Load the delimited file.
- Run the structural audit and inspect each issue category.
- Correct the source or export a working copy for cleanup.
Supported input
- CSV and supported delimiters
- Tables with or without minor structural defects
Worked example
Audit a monthly customer export before importing it into a CRM and catch rows with missing email values.
Limitations
- Structural checks do not prove business accuracy.
- Domain-specific rules such as valid tax IDs are not inferred.
Troubleshooting
- Fix duplicate headers before column-based transformations.
- Inspect quoted newlines when row widths look inconsistent.
Tool-specific questions
Does validation modify the file?
No, the audit reports issues for you to review.
Can it validate required business fields?
It can reveal blanks, but it does not know every organization’s business rules.
Before you process
Can I use this data quality validator online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
