Before I spell up and usher you done immoderate examples, fto maine explicate however customized fig formatting works.
Custom fig formats are entered successful the Type tract successful the Custom conception of the Format Cells dialog box.

The codification you request to insert present follows a strict order:
POSITIVE;NEGATIVE;ZERO;TEXTIn different words, the archetypal statement successful the customized fig format tract dictates however affirmative numbers are formatted, the 2nd statement dictates however antagonistic numbers are formatted, the 3rd statement dictates however neutral numbers are formatted, and the 4th statement dictates however substance is formatted.

- A fig with 2 decimal places for affirmative numbers (#.00),
- A fig with 2 decimal places successful parentheses for antagonistic numbers (#.00),
- A dash for zeros (-),
- And the missive drawstring "TXT" for each substance values ("TXT").

If you permission retired immoderate of the arguments by adding the semicolon but not typing immoderate code, the applicable cells successful your spreadsheet volition look blank.

#.00;;;"TXT"into the Type tract displays a fig with 2 decimal places for affirmative numbers, produces a blank compartment for antagonistic numbers and zeros, and displays "TXT" for each substance values.

Even though the values displayed successful each compartment beryllium connected what you specify successful the customized fig format Type field, the existent values of the cells stay unchanged. In the illustration above, adjacent though compartment C2 appears blank (because I omitted the NEGATIVE statement successful the Type field), erstwhile I prime the cell, the look barroom reveals its existent value.
