Find/Change is one of the most powerful tools for document conversion. With it, you can identify properties unique to your imported text and change the content or apply the correct formatting. Take some time to play with Find/Change and you will cut down your conversion time immensely.
Word often treats automatic numbering as content, which (in my opinion) is why numbering in Word causes so much grief. FrameMaker is different. FrameMaker treats numbers as formatting through the Numbering properties in the Paragraph Designer.
If you import numbered items into FrameMaker, be sure to choose the Reformat Using Current Document's Catalogs and the Remove Other Overrides options (see Figure 2 above). This will remove many of Word's autonumbers upon import.
You can quickly change the ones that sneak through by using the Find/Change command. Identify the common characteristics of the objects to be removed, such as common styles applied and consistent numbering patterns.
If the Word paragraph style name (such as Normal+) does not match the paragraph format you want in FrameMaker, use Find/Change to locate and convert all similar paragraphs.
Open the Find/Change dialog. Search for characteristics unique to your text. The Use Wildcards option helps when searching for numbering. In Figure 3 below, the *.\t searches for any characters followed by a period and a tab. This string will typically, but not always, identify numbering which is content not formatting.

Tip: FrameMaker's Find/Change will not find numbering applied with a FrameMaker paragraph format.
Example: In Figure 4 below, the Use Wildcards option allows FrameMaker to use the text string shown to search for numbered items from 10-99, followed by a period and a tab.

Use the Change: By Pasting option to apply the proper FrameMaker paragraph format to the text.
Tip: Use the Change All option with extreme care as Undo will not reverse this feature!
The results will likely look odd, since the appropriate FrameMaker style probably has numbering characteristics making the text appear with duplicated numbers. Ignore the FrameMaker numbering for now; it will not interfere with the next section.
Tip: If you apply a character format that changes color or weight to your FrameMaker autonumbering, you will quickly see which numbers are formatting from FrameMaker and which numbers are content from Word.
