Replace Spaces with Tabs is a free online text formatting utility designed to convert space indentations or space blocks into tab characters. Instead of editing a long list, paragraph, document, or data sample by hand, you can paste the source text once and apply the same rule consistently to the entire input.
Swaps space indents for tab characters. In standard editing, this converts space-based code blocks into tab-based indentations, which helps enforce specific style guides or save spacing bytes. This is especially useful when text has been copied from spreadsheets, PDFs, emails, source code, forms, content-management systems, or exported data and needs to be cleaned before it can be reused. The original wording is preserved unless the selected transformation specifically changes it.
