Understand this tool
CSV quoting
In CSV, fields containing commas, quotes, or line breaks are wrapped in double quotes. A double quote inside a quoted field is escaped by doubling it. This tool accepts that comma-separated UTF-8 structure and preserves unselected cells as written.
AI request parts
Files are parsed locally in the browser, and extracted text is sent to DeepSeek in chunks of at most 500 characters. The interface shows the number of requests before translation starts. AI tools require sign-in and consume one daily free translation or 1 credit per successful request.
Reference guide
| Input | Rule | Result |
|---|---|---|
| id,title 001,Hello | Translate title only | id,title 001,Hola |
| id,title 002,"Hello, world" | Quoted comma preserved | id,title 002,"Hola, mundo" |
| id,title 003,Settings | ID column unselected | id,title 003,Configuración |
Column selection and preservation
Choose which CSV columns to translate. The tool keeps the header row, numeric identifiers, and every unselected cell as written. It accepts comma-separated UTF-8 CSV with quoted cells, so commas inside quoted values stay in the same cell before output. This reduces import errors.
Limits and AI requests
CSV files can be up to 5MB, and translation text can be up to 20,000 characters. Extracted text is sent to DeepSeek in parts of at most 500 characters. The tool shows the request count before starting. AI translation requires sign-in and uses one daily free translation or 1 credit per successful request.
| Input | Rule | Result |
|---|---|---|
| 5MB CSV | Maximum file size | Parsed if under limit |
| 20,000 chars | Translation text maximum | Split into 500-character AI parts |
| 1 credit | Successful AI request | One daily free translation or 1 credit |
Ways to use this tool
Localizing app strings
You maintain an app string CSV with columns for keys, English text, and notes. Select only the English text column and translate it to Spanish. The tool keeps keys, notes, headers, and numeric IDs unchanged. Quoted cells with commas remain in one cell, so the output CSV can be imported without re-mapping columns.
Translating product catalog titles
A product catalog CSV lists product IDs, English titles, and English descriptions. Choose the title and description columns, translate them to Spanish, and leave IDs and other fields untouched. The header row stays in place, so an import script can match columns by name after translation.
Updating support ticket summaries
You export support tickets as comma-separated UTF-8 CSV with quoted summaries. Select the summary column for Spanish translation while keeping ticket numbers, dates, and status fields unchanged. The page shows the AI request count before starting, and you can stop and resume within the same session.
Preparing category labels
An e-commerce category CSV contains category IDs and English labels. Translate only the label column to Spanish. Numeric category IDs, the header, and any unselected columns remain as written. Because quoted labels keep commas inside one cell, the translated CSV can be downloaded and imported without changing your existing column mapping.
