Text File Splitter
Cut a text file or a CSV into pieces that are still readable files. It splits between lines and never through one, so every part opens on its own — and it can repeat the header row at the top of each piece, which is what makes each one a spreadsheet Excel will accept. By lines per part or by number of parts. A whole batch at a time, entirely on your PC.
Cut between lines, never through one. Every part is a whole file.

About Text File Splitter
A 2 GB log, or a CSV with four million rows that Excel refuses to open. The fix is to cut it up — but a file cut at an arbitrary byte is a file with a broken line at each end of every piece, and a spreadsheet with no column headings.
Text File Splitter cuts between lines.
Every part is a whole file
The cut always lands at the end of a line, so no row is ever sliced in half. Each part opens on its own in a text editor, a spreadsheet, or whatever reads the original.
The header on every piece
Turn on the header option and the first line of the original is repeated at the top of every part, and left out of the counting. Each piece is then a complete CSV with its own column names — which is the difference between a file Excel opens properly and a wall of unlabelled columns.
By lines, or by parts
Say how many lines each part should hold, or say how many parts you want and let them come out evenly. Either way the part names are shown before anything is written, so you can see what you are about to get.
It keeps the file as it found it
Encoding and line endings are carried through unchanged, so accented characters and names with apostrophes survive the trip and a Windows file does not come back with Unix line endings.
Parts are numbered in sequence — report 01.csv, report 02.csv, report 03.csv — so they sort in the right order in any folder.
A whole batch
Drop in as many files as you like and they split in one pass. The original is never changed, moved or deleted.
On your PC, and nowhere else
There is no account, no sign-in, no upload and no telemetry. The app has no network code in it at all and works with the connection turned off.

What's new in 2.0.5
- Now takes a whole batch. Earlier versions split one file per run; drop in a folder and every file in it splits in one pass
- The separate CSV mode is gone, and nothing is lost with it: repeating the header row is now a switch that works on any text file, which is all that mode ever was
- Split into a set number of even parts as well as by lines per part
- The part names are listed before anything is written, so you can see what you are about to get
- Encoding and line endings are carried through, so accented characters no longer come back mangled in a spreadsheet
- Part names are unchanged, so a folder half-split by the old version stays one sequence
- A redesigned interface, in light or dark, and it can follow Windows instead if you prefer
