Previews actual slide dimensions and basic text-box positions, and edits text fragments. Master, image and animation layout are not reproduced. Unedited parts are preserved.

Reads and edits current slide body text from the latest edit history and extracts TXT. With loss acknowledgement, regenerates a new text-only PPTX with a basic layout. Previous/deleted content, notes and masters are excluded. Ambiguous structures, dynamic text, OLE, macros and protection are rejected. Restoring original layout/images/formatting and PPT export are unsupported.

Edits basic slide text and converts to a macro-free PPTX. VBA is neither run nor kept. Attached files (OLE) and hyperlinks are kept as they are. Signatures, ActiveX, external resource links and protection are rejected. Saving as the original PPTM and layout preview are not provided.

Page tools and separate AcroForm filling for text fields, checkboxes and single-selection dropdowns. Forms preserve original pages and regenerate appearances using a Korean font. Signatures, XFA, actions and unsupported forms are read-only. Body editing and OCR are unsupported.

Limited HWP 5.0/5.1 body reading, TXT extraction and text-only HWPX regeneration. A separate structure path regenerates only the body, coordinates and dimensions of unrotated paper-relative rectangular text boxes in one section with one outer paragraph. Tables, images, fields, rotation, groups and protection are rejected. Original fonts, lines/fills, precise layout, HWP writing and Hancom validation remain incomplete.

Edits actual body/table text fragments and creates new HWPX files with basic paragraphs. Separately displays original embedded PNG/JPEG images and preserves package parts. Image position, cropping, rotation, effects, full-layout previews and Hancom app validation remain incomplete.

Edits only ordinary body/table text fragments while preserving other package parts. Exact TXT extraction is available. New paragraphs, structures, documents, layout previews and native validation are unsupported or unverified.

Reads only basic strings, numbers and Boolean values, edits them and converts to XLSX. OpenFormula, dates, times, errors, merges and advanced features are rejected. Original ODS export and preservation of formatting/objects are unsupported.

Edits actual slide body text fragments, preserves the package and extracts TXT. Slide notes are excluded. Layout and images are not reproduced as a preview. New documents and slide structure editing are unsupported.

Edits actual table values, searches, performs row/column operations and exports UTF-8. Delimiters, quoting, line breaks and BOM are preserved within the declared scope. Exact data export is distinct from spreadsheet-safe export that escapes formula-like values. Rewriting the original encoding is unavailable.

Reads actual body text through the semantic structure of real 2013 IWA files and extracts TXT. Limited to the main body and supported text boxes in Pages, current slide shape text in Keynote, and stored table values in Numbers. Recalculating Numbers formulas, editing or saving original Apple formats, and restoring the full layout are unsupported. The separate embedded JPEG may be outdated or show only part of the document.
