Free online XLSB-to-NDJSON converter — upload a XLSB file and download a NDJSON. Fast, private, no signup.
Drag and drop your XLSB into the converter above, or click to choose it. Large files upload straight to storage with a progress bar — and we detect the real format from the file's bytes, so even a mislabeled file works.
NDJSON is already selected as the target. Any options that apply to a NDJSON — quality, resize, rotate and more — appear automatically; tweak them or leave the defaults, then start the conversion.
Your NDJSON is ready in seconds. Download it, inspect or strip its metadata, or share it with a private link — your choice.
