This braille translator turns plain text into Grade 1 Unicode braille, and turns those cells back into text.

The output of this braille translator is Grade 1 braille, also called uncontracted braille. Each letter keeps its own cell, so a word is spelled the way it is written.
Grade 2, the contracted code used in most published books, folds common words and letter groups into shorter signs. Grade 1 is the form used here because every cell maps back to one character. The conversion stays predictable, reversible, and suited to teaching and to basic transcription.
A capital letter is the same cell as its lowercase partner. Grade 1 puts the capital sign, dot 6 (⠠), in front of the letter. H is two cells: ⠠⠓. The extra cell tells you the case. It is not a second spelling of the letter.
Digits reuse the cells for a through j. The number sign, dots 3-4-5-6 (⠼), sits in front of a run of digits, and the cells that follow are 1 through 9 and 0. 7 is ⠼⠛. When a letter from a to j follows digits in the same word, a letter sign, dots 5-6 (⠰), marks the return to letters, so 1a is not read as 11.

Grade 1 uses one cell shape for a letter, upper or lower case. The capital sign, a cell with only dot 6 (⠠), is written immediately before the letter. “H” is ⠠⠓: the first cell is the indicator, and the second cell is h.
Digits reuse the cells for a through j, standing for 1 through 9 and 0. A number sign, dots 3-4-5-6 (⠼), is placed in front of the run so those cells are read as digits. “7” is ⠼⠛, the cell for g with the number sign before it.
Switch the direction to Braille to text and paste Unicode braille into the box. Capital signs and number signs are read back into uppercase letters and digits. A string this page produced converts back to the same text.
This braille translator writes Grade 1, uncontracted braille, one cell per letter. Grade 2 shortens common words with contractions, and those short forms are not produced here. A contracted book will not match this output line for line.
Period, comma, question mark, exclamation mark, apostrophe, hyphen, colon, and semicolon each have a Grade 1 cell. Letters and digits are covered too. Any other character is left unchanged so you can see it was not converted.
