The conversion tool supplied with 010 Editor can be used to convert bytes from one character set to another and can also transform linefeeds from one type to another. Select 'Tools > Convert' or press Ctrl+T to open the Convert Dialog.

In the Convert dialog choose which character set to convert from using the Source Character Set drop-down list. The source character set will automatically be filled from the current File Interfaces. Next select which character set to convert to using the Target Character Set list (by default the target character set is the same as the source). To not apply any special conversions to the linefeeds of a text file, leave the Target Linefeeds list set to '(No Change)'. Selecting a linefeed type from the Target Linefeeds list will transform all linefeeds found in the file to the indicated type. The Convert dialog can be used to only modify only the linefeeds by leaving the source and the target character set the same. See Working with File Interfaces for more information on character sets and linefeeds.

If no bytes are selected in the file when the conversion is performed, the conversion will be applied to every byte in the file. If a selection is made the Conversion may be applied to just the selected bytes by clicking the Options button and choosing the Selection toggle (the default). Alternately, select the Entire File toggle to convert the whole file. Sometimes there is no equivalent character when converting data from one character set to another (for example when converting Unicode to ASCII). Any characters that the dialog cannot convert will be assigned the byte value listed in the Replace Invalid Characters With box (the default is the space character 0x20).

Clicking Convert will perform the conversion or clicking Cancel will close the dialog. Double-clicking on an item in the Target Character Set or Target Linefeeds list will also perform the conversion. Note that if converting a whole text file, 010 Editor may automatically change the current File Interface.

Files can also be converted to other formats using the 'File > Import Hex...' or 'File > Export Hex...' tools (see Importing/Exporting Files for more information).
