Concatenate Files
Combines two or more files in a document account into a single output file. Operates byte-by-byte — useful for plain-text formats (CSV, log files, JSON Lines) where simple concatenation produces valid output.
Inputs
Section titled “Inputs”- Source files — list of files to concatenate, in order
- Output path — destination for the combined file
- Separator — optional byte sequence inserted between source files (commonly a newline)
Output
Section titled “Output”A single file containing the contents of all source files in the order listed, joined by the configured separator.
Common Uses
Section titled “Common Uses”- Combining daily log files into a monthly archive
- Merging CSV files that share a schema (drop headers from all but the first)
- Joining JSON Lines exports from multiple sources before processing
Not For
Section titled “Not For”- PDFs — use Merge multiple PDFs instead
- Binary formats with headers (XLSX, ZIP, image files) — concatenating bytes won’t produce a valid file
