Convert data from Fixed-Width Text to other file types
Convert data from other file types to Fixed-Width Text
What you can do with the Fixed-Width Text Convert tools
Fixed-width text is a plain text format in which every column has a fixed character width and no delimiter is used. For N columns you define N-1 widths, for example 10,25,8, and the last column simply takes the rest of the line.
- Convert a file between any two supported formats, in one step.
- Batch convert a whole folder of files in one run.
- Convert files larger than 4GB, with low memory usage.
- Column widths can be detected from the data (measured width plus 15% slack), or set by hand.
