Are formulas preserved?

ET is the spreadsheet format from Kingsoft WPS Office, the Chinese answer to Excel. It dominates corporate and government IT in mainland China, Hong Kong, and increasingly Southeast Asia, where Kingsoft has aggressive OEM bundling deals with PC manufacturers. The format is binary, structurally inspired by .xls but with its own opcodes, embedded CJK font hinting, and occasionally macro modules written in WPS's VBA-compatible scripting layer.

Westerners encounter .et files most often when a supplier in Guangzhou emails a quotation, a research collaborator in Beijing shares lab data, or a translation agency in Taipei sends a glossary. Excel and Numbers both refuse to open the format. LibreOffice has partial support but mangles complex formulas. heic.now converts the spreadsheet to HEIC by rendering each used sheet region as a styled table, preserving column widths, merged cells, and basic conditional formatting where the source declares it - then HEVC-encodes the render at roughly half the bytes a JPG snapshot would need.

Typical uses include reviewing a supplier's price list on an iPhone without WPS installed, keeping an immutable audit copy of quoted figures in a compliance archive, or filing data snapshots into Apple Photos and iCloud where the smaller HEIC footprint compounds across hundreds of files. For long sheets, the converter paginates so each image stays readable. Recipients on Windows or in chat tools may not open HEIC - route the output through /heic-to-jpg for them, or build a portable bundle with /heic-to-pdf.

Reasons to convert ET to HEIC usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts HEIC uploads.
• You need a feature unique to HEIC (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that ET doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the ET → HEIC tool on heic.now.
2. Drag your ET file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to HEIC. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Trim the used range in WPS before export - .et files often include thousands of empty rows that bloat the output.
• Macros and formulas evaluate to their last cached value; recalculate in WPS first if the data depends on volatile functions.
• Use Page Setup in WPS to set print area; the converter respects this boundary.
• For multi-tab workbooks, each sheet renders as a separate HEIC.
• Avoid embedded charts in tiny cells; they render at low resolution. Resize before conversion for crisp output.
