Conversion Validation Software
Trust Every Conversion with DeltaCheck
Automated validation for file and data conversions, catch differences, measure quality, and sign off with confidence.
Validate Conversions with Total Confidence
Ensure accuracy in every conversion or migration project with automated checks that flag additions, deletions, and modifications between the source and target files before anything goes live.
How does DeltaCheck fit alongside our conversion tools?
DeltaCheck works after your chosen converter, checking the output against the original to highlight differences and confirm the quality of the conversion.
What happens if changes are found?
A detailed HTML report is generated. Each change is clearly marked as an addition, deletion, or modification, with the precise content path to help you locate it quickly in your system.
Can we set tolerances so minor changes don’t fail the run?
Yes. You can ignore certain changes per element or path. If changes stay within tolerance, the run can still pass.
Does DeltaCheck work with Word conversions?
Yes. DeltaCheck validates Word document conversions as well as XML, HTML, DITA, DocBook, and many other structured or semi-structured formats.
Reduce Risk in Every Migration
DeltaCheck automatically analyses your source and converted files and highlights every difference in a clear, actionable report. It removes manual checking, accelerates project timelines, and delivers audit-ready proof of accuracy for every conversion or migration.
