High-volume data work, moving millions of records regularly as part of a job or workflow, needs a tool that treats that volume as the normal case rather than an edge case it merely tolerates.
Million by Million Rows Copier is built specifically for high-volume copying, with a session capacity of up to 50,000,000 rows, SQLite-backed storage that stays responsive regardless of scale, and a chunk-based workflow, Copy Next Chunk producing pieces by default of 1,000,000 rows, designed for repeated, sustained use.
Load your high-volume dataset once, by pasting with Ctrl+V or loading a file in any of 33 supported formats, and the app is ready to work through however many chunks the session requires, with each chunk including the header row automatically.
Parallel worker threads with independent SQLite connections keep high-volume sessions efficient, building the next chunk while auto-saving the previous one, so the throughput stays reasonable even across dozens of chunks in a single session.
Chunk size adjusts anywhere from 1 to 10,000,000 rows, letting you tune the app's throughput for your specific high-volume workflow, whether that means many small chunks or fewer, larger ones.
Everything runs locally on your PC, aside from a one-time license check. Loading, chunking, and exporting all happen offline, with your high-volume data never uploaded anywhere. Data analysts and engineers moving large extracts between tools, database administrators handing off query results, finance and accounting teams transferring big ledgers, operations and reporting staff assembling data from many sources, and anyone who has ever tried to paste more rows into Excel than it was willing to accept, all use the same underlying workflow. Virtual rendering keeps the loaded-data view smooth even at the upper end of the app's capacity, and every worker thread runs its own SQLite connection in WAL mode, so nothing here depends on your PC having an unusual amount of memory to spare.

Is this tool suitable for regular, ongoing high-volume work?
Yes, the underlying design, SQLite-backed storage and parallel background processing, is built to handle high volume as the normal case rather than an occasional edge case.
Does throughput stay consistent across a long, high-volume session?
Yes, parallel worker threads keep chunk building and disk saving running efficiently regardless of how many chunks have already been processed.
Can I tune the tool for a specific high-volume workflow?
Yes, chunk size can be adjusted from 1 to 10,000,000 rows to fit whatever throughput your specific workflow calls for.
What's the maximum volume this tool supports per session?
50,000,000 rows in a single loaded session.
Does this work on both Windows 10 and Windows 11?
Yes, Million by Million Rows Copier is built and tested for both Windows 10 and Windows 11.
Is my data safe when using this tool?
Yes, all processing happens locally on your PC; no data is ever uploaded, so proprietary or sensitive records stay fully under your control.
Where do saved chunks and exports go by default?
A default output folder under My Documents is set automatically at startup, though you can choose a different folder before loading begins.
Can I use this on files stored on an external or network drive?
Yes, files on local drives, external drives, or mapped network shares all load the same as any local file.
What happens if the app is closed partway through a session?
Each chunk is saved to disk automatically the moment it's copied, so a closed app or crash never loses more than the chunk that was in progress.
