Convert Text to Numbers

Convert numeric text into real spreadsheet numbers without silently damaging identifiers.

Choose a scope, analyze numeric-looking text, review protected values, then convert safe cells to real numbers.

Paste Data

Copy cells from Excel or Google Sheets and paste them here.

Import a spreadsheet file

Import CSV or XLSX data into the current dotXLS workspace. Files are processed in your browser.

Tools

The first row is protected as the header. Safe numeric text can be converted; identifiers and precision-risk values are protected.

Convert Text to Numbers

Values with more than 15 significant digits are always protected to avoid Excel precision loss. Scientific notation, percentages, dates, phone-like values, and mixed text are not converted.

Undo and Redo controls are available with the current grid.

Paste spreadsheet data to create your workspace.
