How to Upload Your HWP·HWPX Business Plan Without Converting to PDF

#File Formats Used in Major Government Grant Programs

The 2026 Pre-Startup Package distributed its application template as an .hwp attachment. The K-Startup Innovation Startup League provided both an .hwpx file and a PDF form, and the Public-Private Open Innovation program also adopted .hwpx as its standard distribution format. The Small Business Growth Support program from SEMAS likewise used an HWP attachment form. Because the templates founders receive and fill out are HWP-family files, it matters practically whether you can feed the working original directly into an analysis tool — rather than a printed export.

#Why Tables Break During PDF Conversion

Until major AI services officially announced HWP·HWPX support in April 2026, most AI analysis platforms could not process HWP files directly. As a workaround, printing an HWP file to PDF and uploading the result became standard practice. This conversion path, however, repeatedly caused table structure to break.

PDF stores text as fragments with position coordinates. When an HWP file is converted to PDF, table cell boundaries, merged cells, and multi-column layouts are flattened into a text plane, and the relationship information telling an AI which text belongs to which cell is lost. When an AI tries to extract item-level evidence from that flattened PDF, it may reconstruct row-and-column relationships incorrectly, causing feedback to diverge from the original intent. Table corruption and layout damage during HWP-to-PDF conversion is a well-documented problem that occurs regardless of which conversion tool is used.

#Step-by-Step: Uploading HWP·HWPX Files Directly

You can select an HWP·HWPX file directly on the OpenSeed upload screen. Just upload the original grant form file without converting it to PDF.

1. Fill in your business plan content in the HWP or HWPX template downloaded from the grant announcement, then save the file.
2. Before your final save in Hangul (the word processor), confirm the file format. Save .hwpx templates as .hwpx and .hwp templates as .hwp — keep the original format.
3. On the OpenSeed upload screen, click the file selection button and choose your completed HWP or HWPX file.
4. Enter the name of the target grant program as well; this causes the evaluation criteria for that program to be reflected in the feedback.
5. Analysis begins once the upload is complete and takes a few minutes. Check the report when you receive the completion notification.

#Pre-Upload File Checklist

Even when uploading the original file directly, problems within the file itself can prevent table structure from being read correctly. Check the following items before uploading.

• Confirm the file was saved normally in Hangul 2010 or later. Very old HWP files may have limited structural accessibility.
• For any table cell that contains only an image with no text, add a note in the cell or nearby to supplement the content.
• When using 'Save As' in Hangul, verify the format is set to HWP or HWPX. Files saved in other formats such as Web Document (.htm) may cause an error on upload.
• If the file size is unusually large, compress or remove high-resolution images unrelated to the main content.
• If the grant announcement explicitly states 'PDF submissions only,' follow that instruction. The file you upload to OpenSeed for analysis is separate from the file you submit to the grant portal.
