# phrase api 422 unprocessable entity on locale upload

## TL;DR

Fixes the Phrase API 422 when an uploaded locale file fails validation. Fix the file format or encoding, then re-upload. Use when the API returns 422 naming the upload. Not for 401 auth errors.

## The error

```text
{"message":"Unprocessable Entity: The uploaded file could not be parsed. Check the file format."}
```

## Fix it

### Step 1: Validate the file locally

```bash
node -e "console.log('parse the locale file with a strict parser and read the first error')"
```

Expected: You get a concrete parse error with a line number.

### Step 2: Fix the format or encoding issue

```bash
node -e "console.log('repair the syntax, save as UTF-8 without BOM')"
```

Expected: The file parses cleanly in the strict parser.

### Step 3: Re-upload the fixed file

```bash
node -e "console.log('upload again and confirm the API accepts it')"
```

Expected: The upload returns success.

## When to use this

- Phrase upload returns 422
- The error mentions parsing the uploaded file

## When NOT to use this

- The API returns 401, the credential is the problem
- The upload succeeds but keys are wrong, check the file content

## Tool and version compatibility

- Phrase Strings API v2
- JSON, YAML, PO, and XLIFF upload formats

## Variant phrasings

### 422 only for one locale

That file has the syntax error. Validate each locale file separately.

### file parses locally but still 422s

Phrase is stricter than your parser. Check for duplicate keys or bad escapes.

## Why it happens

Phrase validates uploads strictly before importing. A malformed file that a lenient local parser tolerates is rejected with 422 so bad data never enters the translation memory.

## Edge cases

- BOM bytes at the file start break strict parsers
- Duplicate keys are valid JSON to some parsers but not to Phrase
- YAML indentation errors are the most common 422 cause
