How to Fix MiXeD cAsE Text Quickly | Case Modify
Normalize inconsistent capitalization from PDFs, phones, and legacy files—then restore proper nouns correctly.
Identify the target style first
Body paragraphs usually need sentence case. Headings may need title case. Database keys and URLs often need lowercase or snake_case. Converting to the wrong target creates a second cleanup pass.
Convert, then restore exceptions
Run sentence case on the block, then fix: brand names (iPhone), acronyms (HTML), people and places, and chemical symbols. Keep a scratch list of replacements for recurring projects.
Watch for line breaks and lists
Converters treat each line independently. For numbered lists, convert after assembling the list or fix numbering manually if lines merge incorrectly.
Prevent mixed case at the source
On mobile, disable auto-capitalization when taking notes that must stay lowercase. When exporting PDFs, prefer selectable text sources over OCR scans when possible.
