How to convert tabs to spaces without extra text modification

[Cypress]

Sorry for my bad english.
Needed only tabs to spaces conversion, but when i am using AStyle plugin with custom settings and only "Convert TABs to spaces" selected result is:
Before

if( expression )
{
    return 1;
}


After

if ( expression )
{
    return 1;
}

What about space after if? Workarounds, another ways to solve this problem?

(as much as i hate to state the obvious) search and replace?

Needed only tabs to spaces conversion, ...

Have you heard of a nice utility called Swiss File Knife? Use it and you can convert Tabs-to-Spaces without loosing formatting. Download it from-

http://sourceforge.net/project/showfiles.php?group_id=160478

To convert tabs to spaces, type the following command at command prompt.

Code Select Expand

sfk detab=4 <filename>

It will replace each Tab with 4 spaces.

Thank you very much. 'sfk' works wery well, without lossing formatting. Tabs was converted AND columns of text is correctly aligned  :

Code Select Expand

#define US_SC_RBC   0x01
#define US_SC_8020  0x02
#define US_SC_QIC   0x03

search->replace... is works too, but code look messy:

Code Select Expand

#define US_SC_RBC    0x01
#define US_SC_8020    0x02
#define US_SC_QIC    0x03
