Challenges when translating Excel files

Thai script uses unique characters. These often break during conversion.
Broken fonts are a common issue.

Cell sizing is also difficult. Thai text is often taller.
Page breaks will likely shift.

Formatting is very fragile here. Borders and colors might vanish.
Lost formatting ruins professional looks.

Formulas are the biggest risk. Logic can break during edits.
Manual errors cause huge problems.

Font and Encoding Issues

Thai fonts require specific encoding. UTF-8 is usually the best.
Older files may use ANSI.

Incompatible systems show strange symbols. This makes the data useless.
You must check your settings.

Conversion tools must support Unicode. This ensures the text reads.
Proper encoding fixes most errors.

Layout and Cell Alignment

English words have different lengths. Thai sentences are often shorter.
This affects your column widths.

Hidden rows can be missed. Always check your hidden sheets.
Alignment requires constant manual adjustment.

Merging cells creates more trouble. Layouts break when text expands.
You need a smarter solution.

Method 1 – Manual translation

You can copy and paste. This is the simplest way.
However, it takes much time.

Translators often miss small details. Human error is very common.
Logic errors can occur easily.

This method lacks scalability. Large files are impossible to finish.
Drawbacks outweigh the simple benefits.

Managing versions is quite hard. You might lose the original.
Always keep a backup file.

Managing Spreadsheet Formulas

Only translate the visible text.

A single mistake breaks math. Your totals will be wrong.
