Fixed-Width Text Splitting — Notes

• The columns are defined by widths, not by a delimiter: for N columns you enter N-1 widths, e.g. 10,25,8.
• No delimiter and no quoting are used — spaces are part of the column, so a line is never re-flowed.
• Splitting by object count cuts after a whole number of lines; splitting by column value groups the lines that share the same value in that column.
• A header row is optional and leading rows can be skipped.

How to Split a Fixed-Width Text File (4 Steps)

1. Open Withdata DataFileSplitter and load the Fixed-Width Text file.
2. Choose the split mode: by object count (how many records go into each file) or by column value (which column decides the groups).
3. Check the preview, then choose the output folder and the file name pattern. The header is kept in every file.
4. Click Split — the smaller Fixed-Width Text files are written in seconds. Save the session if you want to run it again from the command line.
