What is CFG?

Configuration (CFG) files store application settings and parameters in plain text, often using INI-style key-value pairs.

What is XLSX?

XLSX is the modern XML-based spreadsheet format used by Microsoft Excel for data analysis, calculations, and charting.

When Should You Use CFG vs XLSX?

Use CFG When...

Reach for CFG when your priority is application config, ini-style settings — its uncompromising quality ensures every detail is preserved.

Use XLSX When...

Reach for XLSX when your priority is spreadsheets, data analysis, calculations — its efficient compression makes sharing fast and storage minimal.

CFG vs XLSX: Key Differences

  • •The core technical difference: CFG relies on lossless compression whereas XLSX uses lossy compression.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Alpha channel support: XLSX lacks transparency support, so semi-transparent pixels from the source will be lost.
  • •File sizes: CFG files typically range Very small, text only and XLSX files 50KB to 10MB depending on data.
  • •Primary audience: CFG is built for application config, ini-style settings scenarios, while XLSX focuses on spreadsheets, data analysis, calculations — pick the format that matches your output requirement.

Advantages of CFG

  • ✓The lossless nature of CFG means file sizes stay reasonable while handling Application config, INI-style settings efficiently.
  • ✓From mobile devices to enterprise servers, CFG is recognized and supported everywhere.
  • ✓The trade-off for CFG's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓CFG is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of XLSX

  • ✓XLSX uses lossy compression tailored for Spreadsheets, data analysis, calculations.
  • ✓XLSX is supported natively on virtually every device, browser, and operating system.
  • ✓XLSX files are compact and quick to transfer, even over slow connections.
  • ✓XLSX integrates seamlessly with all major creative tools and workflows.

  • !CFG to XLSX formatting looks off → complex layouts with tables and columns may shift between formats
  • !Fonts render differently in XLSX → embed fonts or use standard web-safe fonts before converting
  • !Images missing from the XLSX output → ensure images are embedded in CFG, not linked externally
  • !Tracked changes disappeared after converting CFG to XLSX → some document formats don't support revision tracking
