Excel is often the destination for a large CSV copy job, but it doesn't have to be the only path; sometimes the goal is simply getting a huge CSV file split and saved to disk in a usable format, without needing to open Excel, paste into it, and save from there as an intermediate step.
Million by Million Rows Copier lets you copy large CSV data without Excel by using Export Everything As, which writes the full dataset to disk in one go in your chosen formats, CSV, XLSX, JSON, SQL, TSV, or XML, automatically splitting large exports by chunk size, other formats into numbered part files.
Load your CSV, by pasting with Ctrl+V or loading the file directly, and instead of working through Copy Next Chunk and manual pastes into Excel, choose Export Everything As to get the whole dataset saved directly to disk, split into pieces sized however you've set your chunk size.
This is particularly useful when the actual goal is a set of properly split files rather than a manual, sheet-by-sheet Excel workflow, saving the round trip of pasting into Excel and then re-saving from there.
The chunk-based clipboard workflow with Copy Next Chunk remains available too, if you do want to paste into Excel or another destination for some pieces while exporting the rest directly to disk.
Everything runs locally on your PC, aside from a one-time license check. Loading and exporting all happen offline, with your CSV data never uploaded anywhere, and no dependency on Excel being installed or open at any point. 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.

Do I need Excel installed to use this app at all?
No, the app runs independently of Excel; Export Everything As writes output directly to disk without needing Excel as an intermediate step.
Is Export Everything As faster than the chunk-by-chunk clipboard workflow?
For getting split files onto disk without manual pasting, yes, it writes the full dataset in one go rather than requiring repeated Copy Next Chunk and paste actions.
Can I still use the clipboard workflow if I want to paste into Excel later?
Yes, Copy Next Chunk remains available alongside Export Everything As, so you can choose either approach depending on your needs.
What formats can the direct export produce?
Six output formats: CSV, XLSX, JSON, SQL, TSV, and XML.
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.
