About

Data inconsistency is a critical risk in globalized applications. Systems built for Western Arabic numerals (0-9) often fail to parse Eastern Arabic (Mashriq) or Persian (Farsi) digits, leading to calculation errors, broken Excel formulas, and database corruption. This tool eliminates that risk by mapping Unicode specific digit ranges to their ASCII equivalents.

Unlike simple find-and-replace scripts, this engine handles both standard Arabic-Indic digits (U+0660 range) and the Extended Arabic-Indic digits used in Iran, Afghanistan, and Pakistan (U+06F0 range). It preserves non-numeric text, ensuring that labels, names, and context remain intact while strictly normalizing the numerical data for processing.

Formulas

The conversion follows a strict bijective mapping function f where the input character c is mapped to the set of Integers Z:

f(c) =

{

c − 0x0660 if c ∈ [٠ ... ٩]c − 0x06F0 if c ∈ [۰ ... ۹]

Where 0x0660 is the Unicode offset for the Arabic Zero, and 0x06F0 is the offset for the Persian Zero. This logic ensures O(n) complexity.

Frequently Asked Questions

Excel and most programming languages (Python, JS) interpret Eastern Arabic numerals as text characters, not numbers. They have different Unicode values. This tool converts them to ASCII digits (0-9) which are recognized mathematically.

By default, this tool converts digits only. However, if you enable "Normalize Separators", it will also convert the Arabic Decimal Separator (٫) to a dot (.) and the Thousands Separator (٬) to a comma (,) to make the string fully compatible with Western financial software.

No. The conversion logic is written in pure JavaScript and runs entirely in your browser. Your data never leaves your device.

Yes. The algorithm uses Regex to target only the specific Unicode ranges for digits. Letters, spaces, and punctuation remain untouched.
