About TXT Data

TXT (Plain Text) files are the simplest and most universal data format. CleanChart imports .txt files containing tabular data with common delimiters โ€” commas, tabs, semicolons, or pipes โ€” and converts them into charts instantly. The parser auto-detects the delimiter and handles quoted fields, making it easy to chart data from any text-based source.

Plain text files are produced by command-line tools, log processors, database exports, and legacy systems that predate modern formats like CSV or JSON. If your data pipeline outputs .txt files, or you have tab-delimited exports from older applications, you can upload them directly to CleanChart without renaming or converting. The importer treats .txt files the same as CSV or TSV, applying intelligent delimiter detection.

TXT Advantages:

  • Universal format โ€” works on every platform
  • Auto-detects delimiters (comma, tab, semicolon, pipe)
  • No conversion or renaming needed
  • Compatible with command-line tool output
  • Handles legacy system exports
