Convert XLTX to ICB

Convert XLTX to ICB online for free with no sign up, with quality-focused workflow guidance.

XLTX at a glance

XLTX

XLTX followed the same OOXML-era pattern as DOTX: preserve the template workflow, but place it inside the newer package-based office family.

ICB at a glance

ICB

The Truevision line grew out of EPICenter-era PC graphics boards, and several board names ended up surviving as filename extensions even when the underlying raster structure stayed close to the wider TGA family.
