What your files can look like
What to expect: Source-specific sheets are preserved and compatible tables are consolidated. Files that do not safely match the combined schema remain traceable instead of being silently forced together.
Digital text and structured files work best
No website upload required
Select your files inside the downloaded desktop app. Source documents are processed locally on your computer; the website is used for account, licensing and downloads.
Your original files are never modified. FilesStayLocal creates a new output file.
Try it without sharing your documents
Free Access duration: 2 hours. Duration is controlled by the license service.
Review matters when the source is ambiguous
FilesStayLocal is designed to preserve traceability and flag uncertainty rather than invent missing values. Highly inconsistent layouts, image-only sources and ambiguous fields can require human review.
